Although a clear statement would be nice, I think it's pretty clear by now if you put ERP or RP18+, or engage in it, you're at risk of a warning. They're clearly actively going after it or at the very least if anyone reports it for any reason they're going to look to sweep it up before it becomes an issue.

If you're big into the stuff, my sympathies. But I would strongly suggest to stop dancing around what's becoming a pretty clear line in the sand so you don't get banned.
