They may be getting the desired result from the signature campaign now, but in the long run they will not get this result if they close the signature campaign. Because the accounts that are participating in the 1xbit signature campaign, all the accounts are already tagged for various reasons. So it is not possible for an experienced gambler to be attracted to any website promoted by a tagged account.
Big issue here is that most victims who complain about their funds getting stolen by 1xbit usually create an account in this forum specifically to present their case and lodge a scam accusation against them.
These victims had no idea about 1xbit's negative reputation or their shills before joining this forum. This is why most victims are just newbie accounts.
