I am going to clarify this once and for all.

This user contributed big times to my mental health deterioration last year, and he is still not done bullying me.

I use some plugin to replace words with other words in my browser, as just reading "krog" or "krogoth" was triggering anxiety.

Last day, I checked the trust list and forgot about the char substitution.
The nicknames ended up being not existent, hence removed from trust list.

Once I noticed it, I excluded both users straight away.
