In most cases the guys inadvertently brought it upon themselves by acting like a "john" rather than a Sugar Daddy, IOW talking about "sex for money" "PPM" etc., but in other cases it appears that they just pissed off the wrong POT SB who turned them in for stuff they never did and it appears in many cases that SA will act first and ask questions later.
Keep in mind that FOSTA/SESTA has all the "adult" sites running scared, they would rather err on the side of caution than risk having the full weight of the US government coming down on their head. I would love to give the OP some advice on how to get back on, but aside from trying to set up a new account from a brand new device that he has never used to log onto SA in the past, along from using a brand new URL, and most definitely NOT trying to "trick" them by using a VPM or other masking service, I honestly don't know what else to suggest.
The advice I can give, which of course will be of no help to the OP, is to the rest of you using SA, be VERY careful, just as careful as you are when contacting a TER provider to NEVER mention sex for money, PPM, or anything else that could be construed as you looking to pay for sex. ESPECIALLY when using SA's messaging service. It is "probably" safe to have these conversations by text or email, but it's an easy matter for a pissed off and/or BSC POT SB to simply screen shot your conversation and use it to get you kicked off the site. Yes, a lot of POT SB's are BSC and it's tempting to "tell them off", but before doing so, ask yourself if it's worth getting kicked off the site just to make yourself feel better for a minute because "you told her" I live in hooker Siberia, if I were to get kicked off of SA, I would most likely have to (heaven forbid) get a fucking girlfriend (or a couple of them) if I wanted to have any kind of sex life at all.
