I don't think the bethel boys care about individual witnesses. When did they EVER care about individual witnesses? I think bethel monitors this site for trends, or any sign that we are successfully organizing. I remember being approached in chat on how many people I thought would be coming to the silentlambs protest. Stuff like that.
The bethel heavies showed up to shut down Jourles (posting the BOE letters) and the very popular Quotes site (posting contradictions in their literature side-by-side). Those two heroes SERIOUSLY put a knot in their shorts. Richie took a current elder's manual, complete with marginal notes, and sent it out to be imaged.
If a poster were to be 'outed' locally it is likely from them leaking enough personal detail for an enterprising congregation member (or partner) to figure it out.
