"Google Groups" are a current pet peeve.
Signing onto the ham radio group I am a member of, I see a category called "Recent Groups".
Clicking on it, I find a few sites which are ham radio or similar, but a plethora of other crap, including such delights as:
"Foto fantasia"----
"For the discerning voyeur".
"married housewives in singapore""nudist photograph"The last one might be quite legitimate pictures of Naturists trundling around having "nice family holidays", but the first two definitely send out very obvious signals. Probably the lady in the first one & the ladies from Singapore
are quite "voyeur worthy", but I have never had occasion, or the need to look at that group.
A bit further down we have (evidently referring some esoteric computer networking stuff, or whatever.): -
"Salt users"Going lower, it gets a bit dark, with:-
"alt.assassination.jfk"& a few others.
The point of this is they don't offer any way for ordinary users to remove these groups, unless you are an owner/administrator of a Group.
I can understand Google working out that I am interested in ham radio & electronics from the nature of the group, but what tells them I am an old pervy conspiracy theorist?
