@insteadofmoney bitcointalk is the original home of bitcoin where people meet and chat about bitcoin and other alt coins. It is a forum, and as you are allowed to have a signature, there are some people who allow you to use your signature as advertising "signature campaign" and you get paid.

@spread-trumpism might be able to enlighten us more as I haven't got involved with a sig campaign on bitcointalk.

btw followed both of you's.
