platforms like cryptotalk may be available for them,
That site is no way in compare to other crypto-related forums and its considered as dead, almost no new post there upon checking it. Bitcoingarden or altcointalk and reddit is much more considerable than that cryptotalk. While altcointalk seems to be filled with spammers and duplicate accounts, just visiting altcointalk there is a Hhampuz account fraudster by launching a freebitcoin signature campaign.
I'm sure one day they will find a good forum platform for mixer promotion.
