There's no chance for them to revert or clean off their reputation on this forum after all the things that they had done.
I think their intention is not to completely clean up their image, what they want is to gain the trust of people who are new to the forum and those people who don't like the DT system, this signature campaign is just for the purpose of testing this The theory that I mentioned, if he gets exposure on the forum through a signature campaign, even if they are participants who have negative feedback, it will already be a great victory for Dean, he knows how this forum works and must have some malefic plan to get out of this forum with stolen money
Maybe he see that 1xbit still doing good after they got a negative feedback to the community and able to get new players on their site. And this is dangerous knowing the owner of betking easily wash hands after those past incident happen, no wonder that the same scamming will happen again in future so we newbie should be more aware on this and better play on more reputable site rather than believing on a site who already scam people before.
