If you are blocked by someone else then please do not get me involved by asking me to contact the person who blocked you on your behalf to unblock them.
There have been at least three users I can count who did this in the past three years. It should be common sense that people have boundaries and I shouldn't have to say this, but here we are.

At that point you might need to block them, as they might be stalkers.
