i on the other hand, see it in another way, i don't know if it is scam or not but i see that when a signature campaign finally comes out that is not managed by Hhampuz or yahoo62278 which unfortunately has a monopoly here, users who wear their signature do everything to discredit the manager by filling it with red trust and threatening the same thing for the eventual participants, compliments to the closed group and to the free opinion
Start educating yourself on what is a scam and Ponzi scheme it's 100% scam if you want to see other similar sites go to the scam section

There's no monopoly here it's still up to the administrator or the owner of the project who he wants to manage his campaign, it just so happens that these managers are good and all the campaign they've manage now and in the past are all good, I'll have no second thought if I have a campaign and I'm looking for a bounty manager.
