The problem with "equal voice" is that those who are okay to resort to unethical behavior - like spinning up 1000 bots - can "win", over those who constrain themselves to more ethical routes, of speaking or voting one-by-one. Obviously nobody is perfect, but game theoretical analysis shows us that the more unethical someone allows themselves to be, the more they can "game the system" - which DOES work, at least in the short-term.

iirc, blocking someone also prevents them from downvoting you. Though I'm not positive that that works when you, as an individual user, block an entire instance. So if there was lets say 10 people that follow you around downvoting literally everything that you do, blocking them would mean that either you would have put a stop to that, or else they would have to spin up additional bots to continue - which at least forces them to put in additional effort. Unless its an instance user block, in which case you no longer get notifications from their replies, but you can still see their comments, reply back to them, I think vote in either direction, etc. b/c that kind of blocking basically does very little to separate you away from them.

It seems to me that posting is inherently an unequal activity, compared to voting, b/c whereas when we do the former we expose ourselves to criticism, but others who use solely the latter can hide behind anonymity when they vote. Thus the system inherently is not "equal" at all, unless we could either post anonymously, or else if we could see who is doing the voting. I might not even mind if I got 40 down-votes, all from hexbear.net, lemmygrad.ml, and lemmy.ml - I probably would wear that accomplishment as an achievement with pride:-) - but in that case I would want to know that that is the case, as opposed to 40 downvotes from non-brainwashed masses.
