Exactly, I'm not discouraging anyone from joining any campaign of their choice, joining a campaign is a privilege and if you can handle that privilege without abusing it then you're free to go ahead joining any campaign of your chosen. The current yobit associated signature campaign now have a reputed manager in the person of @yahoo62278 which is a positive signs since spam will now be moderated by him.

I just used this thread as an opportunity to highlight some disadvantage you should definitely consider before joining any campaign, If you can handle posting high number of posts without spamming then you can go ahead.
