First of all that 1xbet has stopped thier promotion for a long time on this forum , the only presence they have here is through their ANN thread and their too they are not active. Campaign has been close down for many months now.
1xbit and 1xbet are completely different sites. 1xbit is the scam site while 1xbet is a way bigger site who don't advertise their services in this forum. Also, they have been known to restart their campaigns after long breaks. Do your research.
Secondly the mixture which are banned from the Bitcointalk are not that they are doing scams but it is more of on a global level on a government level where the governments are against these mixture technology and therefore the admin of this forum decided to remain on the safe side and cut off advertisements for the mixtures on this forum.
Another mistake. It's mixer(Not mixture). Most of them helped terrorists, money launderers etc which is why they are humungous scams. Think!
