The problim with those account is simple and can't be solved.
They are newbie accounts, wiht few posts and they change ETH address every campaing, is a nightmare to find the main account.

Also if we look at SuperRodrigoBR https://bitcointalk.org/index.php?action=profile;u=2294456;sa=showPosts
we can find those address



... and going on, every single address do not exist on the eth's blokchain!

For this reason I guess they are bumping bots who bump the thread with fake datas.
