An initial reportable post is often a mistake, often just a person not realizing what they have done, and usually it is best to seek clarification FIRST rather than just go off and report and then generate ill feelings without any effort to allow the offender a chance to realize they offended.
Now, on the other hand, a direct flame, a comment submitted either privately or in obvious reply to a response to an already reported comment, and lets face it , this stuff all has time stamps, so we can TELL when a person has been able to see the objection and has willfully ignored it and continued on...... I wholly support a mod stepping in and STEPPING on the offender.
There is no freedom of speech here, this is Susan's place and I treat it like I would treat my kitchen. Invite only and the second the invite was obviously a mistake, I support Susan or a representative of Susan being in a position to make the person feel unwelcome. And I would support this regardless of how much cash had been put in Susan's pocket by the offender. You can't buy off bad behaviour.
