Running BH ads is possible if you use cloaking.
Because obviously, running blackhat ads without cloaking them isn't feasible, that's logical. Google and Meta, especially, are very strict when it comes to BH ads.
if you don't have any previous experience with cloaking but would like to launch BH campaigns, the best solution might be to hire someone to handle all the hassle for you.
as for using cloaking "tools", I mean all those public tools, I'd not recommend that. Hiring a professional that use his own tricks and methods is much better imo.
Been running ads for my clients for a long time and never faced any problems, so yeah, its all about the method and the tools you use (personally I use my own private tools so can't really recommend any tools tbh).
Perhaps you should post a thread in the HAF subforum, lots of guys here that'd be willing to help you
