The basic rule of this website has always been: do not use bots. It is truly not a simple job to catch these, but they always do it in the end and people are not aware that they are caught either. Wetsuite discussed it years ago, perhaps at least 5 years ago, and then Thequin talked about it subsequently more recently as well. We all knew that wasn't right, but there have been just too many people who have several accounts and assert their innocence. Once they were banned following a significant win, they started calling freebitco.in a "scammer."
You will always have people that think they are smarter than the system and think that they will never get caught. When that happens and they get banned, they will cry for help and shout out that freebitco.in is a big scam and blabla. It is something that will always they the same I think.
