After 2 months, it continued (with slightly less spam).
Less spam because most active spammers were banned and the campaign was managed by yahoo62278 after all. He blacklisted many spammers from that campaign and rejected to pay for spam posts.
List of banned participants in the Cryptotalk Campaign. It started with Yobit, then changed to Cryptotalk.
I had a lot of help in that campaign from regular forum users. I would get pms daily reporting users spamming sections and it led to many bans. Even though the campaign was about cryptotalk, once it turned into advertising yobit, the campaign ended. I was not comfortable with the change.
As far as mixers go, I'm too ignorant to have a real opinion. I've never been interesting in using them. I am sure they have good and bad things about them, but I would rather not risk it. Governments, especially the US Government, have a habit of making things their business. Yes, legit users might use a mixer for 10 million dollars worth of transactions, but criminals will use mixers for billions of dollars in bad transactions. The bad outweighs the good IMO.
