..I don't believe the 1xBit signature campaign is legitimate. They are not paying their participants because they use their own accounts.
Well, you don't really have much to do with any kind of analysis.
Check the spreadseet with 1xbit signature campaign participants, how many participants there are and how they write. If you find connections, go ahead - you have a Reputation thread where you can write about your findings.

Good luck!

Is it too much for you to first read the posts you reply to? I mean, I know all 1xbit signature campaign participants are just spammers, but seriously?
I suppose that either these are accounts that are in the hands of 1xBit or in the hands of the manager himself.
