Anyone else “keep” some otherwise-blockable trolls around?

I do, sometimes. Really just so I can see what they’re doing and track their movements, or even just shake my damn head at their dumb bullshit.

I’m torn between whether to “keep” the creepy Egyptian “professor” who thinks he’s entitled to hit on me because I’m not into men and/or the dipshit who keeps sending me the exact same pickup line, verbatim, every five weeks. What do you think?
