That's been in the rules for a long time ;
• Do not post unfriendly or insulting comments or replies to other members., This can start unpleasant exchanges which no one wants to read in an otherwise valuable topic. If someone has posted a rude comment to/about the user, the user itself is asked to ignore the remark and report the offending post for review and deletion.
But this was added due to hurt feelings;
Answering questions:
Please do not reply to a question with a 'Read the TM' or 'Did you search?' type reply that lacks in content. If a question is posted that could be answered from the TM's, provide a link to and details (page) where the answer is contained. Alternatively, if there is already a thread documenting the answer, a link to that thread is also acceptable. On mobile devices, it's understandably difficult to respond with a link. Giving specific information such as the TM number in which the info can be found is acceptable. Or some helpful keyword to aid in searching.
