I think @Reatim wasn't that there is anything wrong with 1xBit launching multiple signature campaigns. What he meant is that these campaigns are not effective. In my opinion, he is wrong. If signature campaigns had no effect, most cryptocurrency casinos would not have carried them out. Signature campaign is the most popular form of promotion on Bitcointalk, so I'm sure it brings relative results.
The signature campaign is great, it's great for gambling casinos or projects with good potential and reputation, it will enhance their potential and their reputation as well but promoting known scam sites will just ruin their reputation further, I don't know if 1XBIT is really getting a lot of good leads but what I'm sure is they are getting a lot of exposure as a scam casino.
