What if I created 10 accounts...? Each one gives feedback to the others... interact a little... They add different people... Etc.... At that point, it will be hard to guess if they are botspam or not, or at least prevent it.
A simple opinion

None of these 10 account are able to decide nothing, they are not inside the wot of the relay
That would be a legitimate way of gaming that.
I've been wanting to kind of figure out a way of looking at npub behavior in general as a spam filter. So for instance, if you created all 10 of those accounts at the same time and they're only replies to where to each other Within a short amount of time of their creation, that could potentially be spammy behavior and could be blocked.
spam filtering really just is a game of whack-a-mole. There's always some way to game a spam filter.
That means the spammers should pay for 10 accounts in paid relays. This is very unprofitable for them. Paid relays drop the incentive for spamming to almost zero
