Selenium Does Click on Firefox but PhantomJS doesn't (Ruby) - ruby

Question

i'm really new to Selenium WebDriver. I write a simple code for out of curiousity. I made an spam bot to open a page, shuffle in online users list and click everyone of them in order. Send some message, close the new window and repeat.
I made this work on Selenium Firefox driver. It seems work good. But i want to do it silent, not opening firefox everytime. So i found out i can do that by PhantomJS.
Here is my working code for firefox:
require 'selenium-webdriver'
def setup
#driver = Selenium::WebDriver.for :firefox
#reklam = 'Some testing message.'
end
def run
setup
#driver.get 'http://c2.me/okanb3'
first_window = #driver.window_handle
begin
#driver.switch_to.window(first_window)
#driver.find_element(link_text: "Shuffle").click
sleep 20
elements = #driver.find_elements(:class, 'shufflelink')
elements.each do |x|
x.click
all_windows = #driver.window_handles
new_window = all_windows.select { |this_window| this_window != first_window }
#driver.switch_to.window(new_window)
if #driver.page_source.include? 'The user is not available right now.' or #driver.page_source.include? 'User account is disabled.'
#driver.close
#driver.switch_to.window(first_window)
else
input = #driver.find_element(:id, 'inputbox')
input.send_keys(#reklam)
input.send_keys:return
#driver.close
popup = #driver.switch_to.alert
popup.accept
#driver.switch_to.window(first_window)
end
end
end while TRUE
end
run
But when i switch Webdriver from Firefox to PhantomJS, x.click method doesn't work. I made some tests and program doesnt go further from click method. After a while program ends with (Net::ReadTimeout) error.
Here is my last try to work it proper;
require 'selenium-webdriver'
def setup
#driver = Selenium::WebDriver.for :phantomjs
#reklam = 'http://peyloride.com siteme beklerim.'
end
def teardown
#driver.quit
end
def run
setup
#driver.manage.window.resize_to(1920, 1080)
#driver.get 'http://c2.me/okanb3'
first_window = #driver.window_handle
begin
#driver.switch_to.window(first_window)
#driver.find_element(link_text: "Shuffle").click
puts "Shuffleandı"
sleep 20
elements = #driver.find_elements(:class, 'shufflelink')
elements.each do |x|
puts "click'e geldik"
#driver.save_screenshot "phantomjs.png"
x.click
#driver.save_screenshot "phantomjs2.png"
puts "click yaptı sonunda aq"
all_windows = #driver.window_handles
new_window = all_windows.select { |this_window| this_window != first_window }
#driver.switch_to.window(new_window)
if #driver.page_source.include? 'The user is not available right now.' or #driver.page_source.include? 'User account is disabled.'
#driver.close
#driver.switch_to.window(first_window)
else
input = #driver.find_element(:id, 'inputbox')
input.send_keys(#reklam)
input.send_keys:return
#driver.close
popup = #driver.switch_to.alert
popup.accept
#driver.switch_to.window(first_window)
end
end
end while TRUE
end
run
As you can see i tried to take a screenshot to understand the problem but screenshot seems really fine. Here it is:
