There is a thing around FS called undue attention to another player. It has always been against TOS, reason being to prevent possible abuse/harassment of players. Best to air concerns privately via PM's to trusted assassins, if you like, but public venting about whether a player is/is not a thief, cheat or otherwise unsavory character just is not allowed by our beloved cow gods. This keeps the peace and makes for quiet enjoyment of the game for us uninterested third parties.
Came late to conversation, so my 2 cents may not apply.
1. no names were given. just friendly info given.
2. A warning and reminder of what can happen including consequences (i.e. live with it - unless provable violation of HCS rules).
3. A reference to support was advised.
4. If really bad a chance to request aid (no, actual aid) from allies. If ... (just censored stuff) ..., then gold is gone and shrines disappear. Need aid. Also, important to copy important info like allies, Guild history, shrines, etc. Hard to rebuild from losses when one does not know what was lost.
5. There used to be a non-HCS website that kept track of troublemakers. i do not know if it still functions.
Remember, Peace is nice, but War spends FSPs and stamina !
