Since version 1.4.0 FTT has pattern anticheat system. The main goal of this system is to determine cheat traffic from traders by comparing click pattern for this trader with overall click pattern statistics. Click pattern is statistics of clicks on different links on your site. Script will compare this statistics and will show you divergence in percent.

To enable pattern anticheat system, please, follow these steps:

1. Add to your links parameter ac=. You can name value of these parameter as you want. For example, you can name it firstblock for first block of thumbs, secondblock for second block of thumbs and so on. Or you can link every thumb with ac=thumb1, ac=thumb2, ac=thumb3 and so on for all thumbs or links. Statistics of clicks on these links will be used to determine click pattern. Example of links with paratemer ac:
   <a href=/ftt/o.php?url=http://www.somelink.com/?l=link&ac=firstblock>Link</a>
   <a href=/ftt/o.php?url=http://www.somelink.com/?l=link&ac=1>Link</a>
2. Enable anticheat system in Settings->Main Settings->Turn on Pattern anticheat system.
   Also you can set setting Minimum clicks for pattern anticheat system - minimum amount of clicks from trader to start counting click pattern statistics. Before this amount of clicks divergence of click pattern will be 0%.
   And setting Maximum time to count clicks for pattern anticheat system (in hours) - amount of hours to count clicks. By default - 48 hours ( 2 days ). Setting this parameter too high will result in bigger database and possible slowdown of cron script run. 
3. Watch statistics in Main Stats in last column AC ( under parameter AR ). If you see divergence for some trader too high - that's signal of possible cheating.
