I don't have any evidence myself but when I first joined the server and noticed the way he b-hops and flicks to certain targets did always strike me as suspicious, some shots and some hops feel like they aren't cheats while others do, so potential on the toggling, especially with the g-mod playtime he does have. I myself have noticed a couple hops that are very suspicious on such thing as stairs, and other uneven surfaces where he still maintains speed or even gains speed but I'm uncertain if he has any sort of bunny scripts but I do agree with the potential soft aim, I've very rarely seen him miss and when he does it seems like hit-reg. things that strike me as suspicious would be things like 4:44 of your video, where muddy shoots quite a ways from the target and still hits him in the head, but again this could just be "gmod being gmod"
Edit* - 5:25 is pretty blatant soft aim, if you watch in 0.25 he over swings by a tad and it immediately snaps onto the head.
