i literally know IANBU.
I have only asked for one thread to be withdrawn and picked up by the DM.
But many many threads with really very sound advice by posters, helping the OP get withdrawn and often we don’t know why! Example today the thread about the GPs going on holiday. We all said look you’ve just had a baby. Time will fly, they’ll be back soon and let them go on hols (her DP called and told the GPs they shouldn’t go on holiday).
Rightly or wrongly this is a public forum so you have to be mindful of what you post/ask. But it’s also where others come for advice, looking at old threads and then to find they’ve been withdrawn!!
I don’t think IABU but MN are by not giving proper explanations. It will drive down engagement and quality of postings/posters and you’re just getting deleted when you’ve taken time/thought to offer an opinion/help someone out.
