Absolutely. Here's a little info about the recent dox, and since I forgot to include the Discord hijack thing I'll stick that in here as well.
I found an admin of the Yiff Links channel who wasn't just Simba on an alt as most of them actually are. Which was difficult because you can't see the user list of a Telegram channel so I had to do a ton of asking around. One of them found me by chance and started defending Simba from the evidence I was digging up and posting. So I told them a bunch of things that (at the time) I knew Simba had done. They insisted on defending Simba for some reason and relayed everything I'd told them back to Simba and one of Simba's alts who he believed was a different person. Simba then proceeded to become angry with that person for 'opening their big mouth' (they knew too much) and doxed him that same night an hour later.

Block them and never under any circumstances listen to what they have to say' basically. Because many many many of them are banned without reason or because he blackmailed them and doesn't want that information getting out.

For the Discord incident, it's easier for me to just post what's pinned in the announcement channel since it explains everything anyway. I happened to be one of the users he banned during his hissy fit, but everyone he banned was unbanned immediately with their ranks and roles restored. Keep in mind this server has 19.3k users in it.

Yes, he does. There's evidence of him using that information alone to try and coax people's locations out of them by asking vague questions such as "I heard so and so is a disgusting place" or "how's the food at so and so" by Google mapping restaurants in the location he received from the rebrand.ly link when the location is too vague. He's even asked people about bus routes and such to try and narrow down where they actually live so he can use it to blackmail them.
EDIT: Forgot to put this into context. The "Thinker thing" they're referring to is the name of the person who took the screenshots. They're the admin that was banned from everywhere for speaking with me. They told one of their friends about it who then expressed their concerns to Simba, and this was the result.
