How to get only numeric text in recaptcha? - recaptcha

In my site its very difficult in some cases that the given text images in Recaptcha are not clear. This lead to reduce the intreset of login into our site. I needs some help on getting only numeric values in recaptcha.

No, this is not possible. Recaptcha has been designed to avoid any OCR's and automated bot attacks.

ReCaptcha V2 Force Text Validation

With ReCaptcha V2, is it at all possible to force Text Validation when the simple "checkbox" validation fails?
One of our products uses ReCaptcha V2, however one of our clients in Vietnam is uneasy about this, since they seem to get a high percentage of clicks that require image validation, and they think their users won't understand how to do the validation...

reCAPTCHA is accepting random values

I'm using Greg Gilbert's reCAPTCHA validator for Laravel 4 (https://github.com/greggilbert/recaptcha).
I know that reCAPTCHA only needs one word on two to validate forms but my problem is different. I actually have a single word displayed on my reCAPTCHA, the second one is missing. And unfortunately, the displayed word is the "pictured-word", you know, the word for which you can write whatever you like and it will be accepted.
So if it shows number 109, I can write "108" and my form will be accepted.
How to fix that please ?
After some tests, I've found that if I use Firefox's "Private navigation" window, my reCAPTCHA is displaying 2 words instead of 1 as I described here.
It means that if you are connected to your Google account on your web browser, reCAPTCHA "trusts" you a little bit more than a not-connected user and shows you only one word/number.

Algorithm / API for converting HTML to email friendly HTML (for newsletters)

I'm sure this is a very old question, but I could not find a straight answer
I'm looking for a works-mostly algorithm to take regular HTML content, and make it email client friendly.
I can rewrite any nice DIV layout to table layout, this is OK, but is there anything that will do it for me?
Here are my concerns
Overflow content - gmail etc ignores any overflow:hidden, the algorithm should address it
Clipped images - same as above, but here the solution will probably be server side clipping
CSS / Script / non standard tags - the algorithm should remove but keep the general look and feel
DIV layout to table layout, I heard it's a must, but I'm sure it's not an easy task to automate
There are many HTML to PDF converters, but I could not find a good HTML to "HTEMAIL" converter
Is there any standard or proposed standard for HTML for email clients? or is it an open jungle out there?
There is no way to make a converter that will be cross email client compatible. The closest you can get is using templates and adding text in certain sections using php or .net
I've been creating emails for 6 months, and the amount of time you spend correcting email client differences is normally around 50% of the time you spend making the email.
Here is some reading that may help you:

http://www.campaignmonitor.com/css/
As you can see from that last link there is no way to create an algorithm that can sort out all these issues.
Hope this helps
Another option that I've been using is to build the email in HTML or directly in Mailchimp. Once I'm happy with it, using Mailchimp, I click on preview and I get the email in a popup. The source code from the popup is email-client friendly (in tables). I then copy that code and use it for my emails.
Not ideal and a bit of trouble, but so far the best solution I can find.
And before people ask, I mostly us Mailchimp directly, but there is one situation that I have to kick it old school.

Adsense revenue depending on use of Ajax

I noticed that a website like imgur.com displays ads on each page of the website.
This means each time you press "next" to view another funny picture, AdSense refreshes.
But a website where you can scroll to view more pages(such as 9gag.com),
Ajax handles loading of more funny pictures so it's illegal to refresh Adsense when a user scrolls for more funny pictures.
Does this means 50 users staying on 9gag.com for 3 hours scrolling and viewing 300 funny pictures would help 9gag.com generate revenue equal to ONE imgur.com user that views only 1 picture?
Does this also mean I should stay away from Ajax if I wanted revenue?
This was very confusing for me, please help me understand AdSense better.
Thank you!
WEll the problem with fully scripted ajax loaded content is that Adsense cannot read it. Therefore it has a hard time displaying relevant ads, because most advertisers have chosen to target the visitor location and the keywords on the pages. So if Adsense has no text, then most of the time it's not going to be able to serve an ad.
But I looked at 9gag.com and they are using what I think is the ajax version of Adsense, or perhaps the premium version of Adsense which allows for all sorts of things and is quite different from the core Adsense program in many ways that nobody seems to know about, and few are invited. All the big publishers I suppose.
Anyway, if you do end up clicking on one of the posts on 9gag.com you'll see other ads. Granted that the way that imgr.com has things set up should encourage more content viewing per visitor and thus also some more ad viewing, but I wouldn't say that one necessarily has more traffic overall than the other. There are too many unknown factors to determine that. Not something you can do just with looking at a site. That is where having good analytics of your traffic and visitor behavior comes in.

Looking for an anti-spam solution easier to implement than Captcha

I'm looking for a simple anti spam form submission solution, other than Captcha. I've tried implementing Captcha into my website for anti-spam purposes, but it's been too difficult to integrate into the site. I don't get many spam attacks but I'd like to have something in place for the random spam that I get. Does anyone know of something they think would work?
you can add an additional textfield to your form and hide it with css. human users don't see the field, so it should always be empty. spambots usually fill out all form fields and don't know that this one is hidden. if you receive any content in this field, reject the form submission.
Put up something like "What is 3 plus 6?" and give the user a form to type the answer. Any human will get that, including blind ones who can't see a captcha, but no bot will. You don't even need to vary the numbers, really.
