Dosnt bring much because there are still some freaky Users that posts everywhere there ANNs , there are already some who post there ANNs in the Mining section too. And that Users not Newbies !
If they not be allowed to post with that ranks they buy some Accounts and doing that , also if there are some real Users that want to make posts and they cant isnt helping the Forum
1) That's entirely up to Mods, but having more coherent and organized sections will reduce overall spam and thus users will be less inclined to market their coins elsewhere on the forums. But yeah, admins moderating wrong posts in incorrect sections
2) They already do this in mass quantity, most ANNs are made up of 10-100s of fake accounts bumping the thread and further exacerbating spam throughout the entire section (you have to utilize puppets to have any effect).
3) If you're posting a Sale, then you should have some sort of forum reputation. Restricting 1-3 projects from posting because they don't have rank will still be insignfcant in comparison to the hundreds of other projects posting scams, pure shitcoins and spamming their threads with puppets. I mean we're talking about money here, if a person is seeking investments then devoting a small bit of time to prove you're not a scammer on BTT isn't that difficult (ofc this is not fullproof, but will reduce the ease of scamming). Creating that barrier will greatly increase quality of threads and all projects. Again, this is for only the supposed "ICO/Sale" type ANN subsection. Mining/no-cost coins will not have to have these types if restrictions.
Restricting new account from posting in sales is perfectly fine, or account that have not received 1 merit.
Whatever system gets implemented will have repercussions and unforeseen consequences, but if forum mods/admins and etc want to do something to correct the problem, any solution will be better than the current.
I bring this all up because scammers are reposting notable ANN threads, from Nem, DASH and etc, coins in existence and trying to capture unknowing users into their chirade of bad links. What's occurring now is getting out of hand.
Aside from all that, BTT is losing traffic to other sources. I know altcoins is not a focus, but it once was a leader for all altcoins, with a little bit of effort you can reclaim that title and create a semi-safe and clean environment for users.
