This "Marcos" account seems legit. A lot of posts, been on Patreon for over a year, has supported a lot of games. Also, his english is not broken, unlike Rainces', and he seems to have a ton of money to support so many games. If Rainces is indeed venezuelan, it is unlikely he would have that much money unless he was Maduro's nephew/grandson or something like that.
Of course, Rainces' persona may be a disguise for the real "Marcos" behind BBS (it is even a latin-spanish name...). Or both can be together in some kind of scam. Everything can happen. But I would say that it is legit and Marcos has the new version of BBS. I would say that by sunday we will have something.
If I were a patreon, I would be contacting Marcos to have some details.
