Grind was a more a concerted effort at night when he was more on the attack, with those constantly downvoting him outnumbering the upvotes, and it took awhile. Same with BrideofGeorgie, he got it recently, but he must have irritated enough memers over time that they all started DV'ing him. He even started pestering the kids. I saw many lowrated comments of his, but he didn't complain about a timer till a few of weeks before the end.
Vanilla mIce gets upvotes, posting in PoliTicksBooBoo too, as well as his own streams, posting the same meme multiple times. Plus his output in comments. So what he tabulates has been enough to counter it, unless it's slowly building up like it had with them two.
Like with me, Sew, laonsite, Blue Ninja, antithesis, etc, we get plenty of lowrated comments, but more with upvotes so... I haven't heard them of complaining about timers, and laonsite used to get hit hard before he retreated more to PoliToo.
