The begging threads were rife. They weren't called begging threads of course, it was always can't afford Xmas presents for the kids. Or no food in the house, what do I do? Or desperate, please help.
You always knew they were begging threads because the OP always had an answer for why every reasonable suggestion was impossible for them. And they'd say 'not begging, just want advice' then you'd see posters saying 'DM'd you OP'.
And there was once a thread which was deleted after a few dozen posts because it would have just encouraged more begging but it was titled something like 'MN says not to give more than you can afford financially or in any other way so why the anger about MN posters choosing to help people?'.
Which was full of people taking about the times they asked for a posters bank or PayPal details and sent them money. Some a tenner or £20, some more. The most I saw was £500 and there was someone who said they paid for groceries to be delivered to a stranger on MN for months.
There was also a knownbposter who said she was a sex worker and would post things like 'really don't want to have to get a punter' and people sent her money and a couple lived locally to her, DM'd her and reported they'd gone to pick her up and fed her, let her shower and get changed in their house. That was years back. Poster called longsocksandhighheels or similar.
The prevailing attitude was they'd rather take the risk of being conned out of money than be in the position to help someone in need and not, in case they were lying.
However, lots of posters started to alert others on threads that had classic red flags for begging so it became much harder.
MN always took the line of not deleting the threads even if they were reported and just posting the we can't say if OPs are genuine or not so remind posters not to give more than they can afford financially, emotionally or whatever it was they'd say message on each thread.
