You can make a request for me or any moderator to not reach out to you except for server business, and that will be honored. So while it is true, you cant block moderators you can ask us to disengage. perminantly.
Of course the flip side of that is you wouldnt be allowed to comment on moderator posts except for server business as well. Its a two way street. Violating that would be harassment at that point since disengagement was requested.
If you want to make that request in general (not just on this thread) just speak up.
