Let me give you an example on this. Let's suppose my 100$ are stuck at 1xbit and i file an appeal or complain to them. Now it does not matter if fake people / accounts come here and says that their issues are being resolved. i would only trust them only if my own issue is resolved. So i think these tactics won't work not even in the short term.
It's a pointless tactic in this forum for sure, but it could help them in some other sites where their reputation isn't completely messed up. They have all the resources required to keep using this tactic again and again even if they keep failing repeatedly.
Some of the victims who claim that they recovered their winnings successfully pop in and out of this forum quickly which is a noticeable red flag.
