I really don't regret blocking or silencing any instance. I'm sitting here going through my list and I remember why I blocked/silenced each and every one of them.
Every once in awhile I check to see if there has been any growth, but, unsurprisingly, the people who I block PV access for are still the same tired bigots babbling about the same tired shit.
It's remarkable how some people refuse to learn *anything* in the two years I've been here, but that's what bigot do.
