It's funny you should say that. Mate is this
signaturecampaign.org or
bitcointalk.org? Lol. Nobody is forcing you to do sigs. If you think a brand/company/sig doesn't aligns with your believes or knowledgebase, then don't do it, simple. Also you can't just tell managers what to do and what not to. They set the rules not you. And nobody said about limiting yourself in posting only in certain boards, you may post anywhere that interests you. But when it comes to getting paid, posts that are in specified board will be counted. Another thing you said "
signature campaign participants right", I mean what rights? I believe you are old enough to know, "
Signature is a privilege not right ".
I suggest you read this topic
[Guide] Factors to consider before joining paid signature campaigns[5]: Consider boards post count are accepted in.I notice many forum users joins signature campaign without considering the boards they're most active in. I recommend you join a signature campaign based on the boards you're active in, currently I won't join a campaign that doesn't consider Beginner and help board as an acceptable baord for post count. Reason been that that's the board I'm most active and familiar with and enjoying answering questions ask and assisting newbie on the board. Lets say there's a campaign focus on accepting participants only posting on
Development & Technical Discussion baord I won't apply for such campaign since I'm not that familiar with the board and most of my post would be considering off topic as I'll be struggling to meet my post count which might lead to spamming the board and might end up getting ban or removed from campaign.
