...should be a breach of guidelines?
Mostly it can be amusing or eye roll worthy when someone barges in a few pages later without reading more than the OP, and even that is questionable sometimes. Some replies seem based on just the title .
But there have been several threads lately that were quite sensitive , with the posters in dangerous situations,vulnerable,at risk or just in a very emotional state.
And posters kept showing up without RTFT , any of OP's comments or updates and just sticking the boot in and having a go at OP again and again based on a quarter of the information.
If people have form for this and do it repeatedly I think it should count as breaking guidelines, then maybe people wouldn't be so callous and lazy.
