Number 1 and number 4 are obviously not a choice it seems. For some of us 3 isn't a choice either. Number 2 would be the best way, but some of us know that when it happens to us, it was MEANT to be an irritant! At my age, it seems rather childish to "go running to 'Mommy'" and saying "so-n-so is picking on me!!" But on second thought, at least Admin will know that there ARE troublemakers out there and WHO they are.
The only times I've put someone on Ignore is when I've been triggered and can't handle it on my own. Otherwise, I don't block my PMs. I try to work it out on my own.
