I also agree with the above. Even 1 dollar per post or 1.5 depending on the price of Bitcoin is huge money if you're paying for shitposts like some of the members of this campaign have produced. Even if a spammer gets kicked he's still paid by Yobit for what he got before he got caught. This is an enormous waste of money if we count in people who were copying old posts, bumping threads as old as 10 years, and spamming games and rounds with one liners and making more than $20 a day doing so.
A quality post that gets merited and quoted by others is worth more than 20 spam posts and Yobit could easily get a quality post per every dollar spent.
I'd like to play a devil's advocate if I am going to hire an excellent poster with 200 posts and a member rank and a legendary average poster with 8000 posts, who do I hire? I'll go for a legendary average poster with 8000 posts,
This is 8000 posts showing visibility of my ads, people are not only looking for relevant topics but people are also looking for an answer to their queries whether it is a 5-year-old post.
Yobit people want advertising I don't think they will settle for 50 excellent posters they want 300 or more average posters, they want visibility.
This has the trade-off of being an exchange or just a service with a low reputation. As DiamondCardz has mentioned, even though you write a good, instructive, discussable reply, as one person sees the Cryptotalk signature it automatically gives you the vibe of being a potential spammer. On the forum, you mostly see the signature first, then the reply and finally the person who actually posted the reply. If one thread has a billion people with all being Cryptotalk signature members, it sometimes gets annoying. Especially when more than half of those members are just shitposting. If they want visibility. So be it, lower the reward for lower ranks and increase it for higher ranks, put a merit limit and (maybe) include special bonuses?
So far, since the beginning of October, I've reported a lot of people to Yahoo due to violation of rules or just straight up abusing the campaign. A considerable number of them were Sr. Members. Although it will definitely cut the number of people participating, if you were to take out the Sr. Members from the campaign and just double what you are paying to Hero and Legendary members, I definitely bet you that the overall post quality will improve. Having a Hero or Legendary accounts is not easy. Especially if you weren't one before the merit system.
Your idea of paying a person who has 8000 posts might be viable, however, the posts would most likely be outdated, in random threads, on page 295 of Services or any other reason. YoBit also needs "activity" there are hundreds of threads being started every single day, which is basically the dream for shitposters.
I think according to the latest thread of suchmoon is that there are now more than 510 members in the campaign. But how many are actually "worth it"? I know that long posts aren't really the key and one short answer to a good question might be worth 3 long posts, but there are a lot of people who aren't even "posting" or "replying" to me, some posts are no different than "thank you, you're the best" which adds no constructive criticism, thought, idea. Nothing, nada.
YoBit has revived the signature campaign and posting on Bitcointalk, but I am not sure if it's in a good way, or bad way. They can always fix it though. All they have to do is read suggestions and listen to Yahoo.
