Something that just occurred to me is I wonder if pools with multiple validators could attack each other by pulling votes. Imagine if a competing pool, run by a SEM whale, saw you starting pool3, they could then take some of their reserve SEM and use it to fill up a large portion of your pool3 vote capacity.  Then at the most opportune time for them (maybe when they have enough votes to make another validator) they pull their votes from pool3 making it lose its validator status and lowering your payout across all 3 pools (if your treating them as one big pool). Probably not a realistic scenario lol.. just trying to imagine crazy things that might happen.
