@Matt, Commenting on your link dump for ease of access for everyone else. Warning that I'm only checking the posts linked and not the entire threads since I don't have ALL day, it's your job to compile information properly and clearly if you're reporting someone.
1. How is this reportable? Politely talking about changes to a profile on someone's wall.
2. How is this reportable? Just a normal post talking about feats, did you mean to link something else in the thread? There's no swears, hostile language, or being unreasonable here.
3. Since this links to Shrek's post I'm assuming you meant to link to Regis' one underneath. But that's still another non-hostile post discussing feats.
4. Starts off slightly hostile "Any proof, or just empty words and nonsensical scalings?", which is something that usually wouldn't even get a slap on the wrist, but from a quick glance the rest of the thread seems to be normally discussing feats.
5. Literally just asking for a source for a statement. Why is this being reported?
6. This is hostile/out of line, for sure.
7. Hostile/bad behaviour from Regis.
8. This is a long thread (planning on Regis' message wall for a CRT) that I don't want to fully read, but Regis calmly asked Matt to stop posting there multiple times. While those requests were stern, I didn't see them go out of line/stop being polite (and Matt's obstinate refusal to leave didn't help things out).
9. Again, I only checked the first couple of posts but it seemed to be polite discussion about feats.
10. This link has a post number of "150" even though there's only 72 posts in the thread. Anyway, from Regis' posts the worst thing he did was say that Weekly was lying two or three times.
11. Only checked the first few posts after this mention, but it seems like Weekly/Regis were both being slightly hostile. Regis was calling Weekly a liar, Weekly was using all caps sometimes, they were both accusing each other of bias and downplay. Not a pretty sight.
12. I checked a few posts in, it was mostly a civil conversation but Regis was being a little sarcastic and said that Weekly wanks characters.
13. I checked a few posts deep, Regis/Weekly were just arguing about feats. The most hostile thing I saw was Regis calling some evidence vague and unreasonable.
14. I checked partway into the thread, the most hostile thing was calling some feats "flimsy".
