No.

You have to decide what bounty you want to participate in. There is no good or bad here. Because a well managed well raised ICO project may end up with a lot of problems in future while another one may be able to pay out bounty tokens nicely and keep every hunter satisfied. It is more a subjective sense that bounty should be done by those who actually are interested in that project and not merely looking for a part time income through that bounty. For social media though, payouts are very low and not worth your time. You should work on your posting quality and join a bitcoin paying signature campaign.

In my opinion the best Bounty campaign in September 2019 is the signature, because I have followed the signature several years back and the results are pretty good, but if you want to have even more prizes, you can join all bounty campaigns like Content Creation and Facebook, but that is also if you are already proficient in following the Bounty campaign and also can manage the time correctly.
