What to do about doxxers & Racists?

I'm a Roblox youtuber who is conducting an investigation on a known Roblox predator for a documentary-styled video. Me and some other people had found out that there was a group of doxxers, racists, and just a bunch of overall bad people not directly associated but still inserting themselves into that drama. For the sake of the investigation and my video, I made an alt account and "spied" on them, I ended up getting most of the information needed. I'm just wondering where to go after that, they're doxxing innocent people and I don't stand for it at all, but I know if I were to say something, or even post the video, id get doxxed as well.

Is there anything I can do about this? All I have are some discord/Roblox accounts of theirs.

I've been trying to be as safe as I can about it. Using alts, discord in browser with operas vpn, documenting everything I can. These people are genuine scum and will do anything in their power to ruin my online life if they found out. Please help.
