who after being doorstepped by a Sky News journalist called Martin Brunt, confronted about all this, promptly disappeared and was found having killed herself?

here's a couple of links:

the whole thing seems to be a mess. no-one should be made to feel bad enough about anything to commit suicide. trolling is bad, but given this, and that quite a few studies now link internet trolling and psychopathy, what do you do about anything?
