At first I was genuinely worried about sending a message like this, out of fear what they may do when/if they stumble across this, but I think this is super important to address. The last thing I’d want to happen is for them to start targeting someone else, or another wiki.
It’s been a while since I was on here, where do I send this to?
Who do I contact, or can anyone contact someone for me? Is it a problem if I am unable to email someone?
I may be deleting/turning off this account later on, as I don't want to be targeted. I don't know what this person can do, and I do not feel safe on Fandom with them around.
You should use Special:Contact with every thread you can find where they are threatening others. Sending malware is not okay and staff will act on it if they have proof. If they are crosswiki vandalizing, you can also contact VSTF
