hej, i know people can click on your ads and get your account banned. but if i remove those ads and only put that search block, can they click bombing my account again with searches queres?
Yep, if anything it is much much easier to make a bot to run automated searches than it is to click on ads. Lots of submission bots can even be modified to do this.
Actually it is not easier nor harder. For instance, if I was going to make a bot, I would make it in ruby. The code looks something like this "LITERALLY". require 'http-uri' open 'http://www.site.com' searchbox.fill_text = 'A Search Phrase' click_button 'search' Ruby is rediculous. Just remember anything can be done, and it is getting easier and easier to do by the day
