Over the last few years, I’ve encountered many untagged pros. They often follow the same patterns. I message them, they respond, but never visit my profile. I estimate about half (in my experiences) immediately try to exchange some sort of contact info outside of CC.
When the combination of the above happens, it has always (no exaggeration) led to an untagged pro. I always report them and most times they are banned. The rest of the time their accounts are paused and then they later become tagged pros. Personally, I don’t think they should be allowed to become tagged pros if they started breaking the rules right away but I’m not looking to debate that. CC can handle that how they see fit.
I’m just posting to see what other methods you all have seen by untagged pros.
