1. It think some form of indemnification should be in place for bad advice from LHO's. The LHO should say IDK if they don't. If the LHO says it's okay but it turns out not to be (assuming the player did not trick the LHO somehow), then a. The player is cautioned but not punished, b. the LHO is evaluated as to whether they are fit to remain an LHO, but not punished unless malicious intent is found.
2. In this community, we must define the standard for "offensive". I like to reference a PG movie rating -- if that is correct. I have not thought through all the international website - culture concerns. But it should be spelled out, not assumed that everybody knows what is and is not considered offensive.
3. Revealing personal information about players, that was not gained in-realm, should not be condoned. It is not exactly harassment, but can be damaging via invasion of privacy, and can lead to safety concerns.
