Yet knowing that this person has had issues with depression you still felt it okay to downvote their rep to -3 and effectively hide any conversation from them. If you don't see an issue with that, then I don't think you have any sensitivity to mental health issues at all.

I've just gone through some of the accounts last comments, having to reveal each individual comment you downvoted, and I don't even see spam. I see discussion and each comment being unique.

And incidentally, yes, many people are quite capable of not letting their depression be apparent and do fantastic jobs for their clients, so I'm not about to judge someone's ability just because it's been disclosed that they have had depression.
