I recall you from years ago as cicero and Hatuer was it maybe --- if one of the posters you referred to here is correct about your nic list.
I've never blocked anyone, but like you I have managed quite a fan list too, and suffer essentially the same types and forms of harrassment -- if that term apllies. The only diff is I pretty much confine myself to BB, so their is no following me around but there.
As I see it, with the feature I suggested at least the BS responses wouldn't be soiling up your post, and who knows, maybe the idiots would find some cajones and actually address what you TPed in one of their own. How funny could that become? Imo as well, this feature would also take away this fav form of harrassment of the dedicated common rightwingnut troll, who might wilt from boredom if all they are left with is an occasional idiotic TP not worth acknowledging with a response. I haven't posted over on BOTF for years, so I can't speak to the talents of the trolls I'm sure are there now, but those on BB these days are pretty uncreative and witless.
I've learned to love their "-" and generally non-topical efforts at rebutting what I post. The thinking people know what's what, and if I was posting for an audience, they'd be it, not the laughing hyenas that only have strength in their numbers, not themselves.
