I recommend visiting twister's link. It's a really nice and clear summary of the different signature campaigns here although sometimes the information isn't up to date.
Put "Bit-X sucks" in your signature space.
Strange to see Bitmixer is also there. Other than their slightly low payouts for senior members and up, their signature campaign has been generally quite well received since everything is automated and payments are usually processed quickly.
Was just removed from the Bit-X campaign, not for spam, just due to them prunning membership.... What's the best campaign to join now?
the highest pay per post campaign as of now is DaDice.

Most of these have stricter requirements compared to typical signature campaigns. CoinRoyale, for example, pays 0.04 BTC for a minimum of 20 posts per week:
