No dude, I'm telling you, there is one dude that has been using the same vps/znc for 10+ years, at one point, while he's talking, the nick goes from for example green to white, after 1-2hrs of being there even, and it stays white until mIRC restarts then it's green again. znc here too so, no parts and no rejoining.

I noticed with other nicks too, they've had the same host for years.
