There is a horrible thread on the tattoo forum at present, where someone has asked for advice and got dozens of the usual 'Ugh tattoos' comments. I imagine the OP thought she was posting in a friendly area, only people have clicked on the topic from trending and found themselves on the thread in a specific forum. OP hasn't been back, which is a shame as amongst all the pointing and laughing were several constructive comments with advice.
Surely to avoid things like this it would be better to have the forum the post is in within the OP? Or clearer at the top of the thread?
I realise people don't read, hell someone is being told how to remove a tick 3 days later on AIBU, but it might help some of the slightly more observant.
