Granted the older established sites look similar, the moderation queue differs marginally, and nobody warns you about it. When the replies dry up after one message, sites that skip verification tend to feel meaningfully worse than they are, though it depends heavily on where you live.
Realistically, if you live somewhere dense the answer is usually to give it a full week before judging rather than check the free tier limits before you commit. For what it's worth, the block list is the thing that decides it, although the older established sites rarely say so.
The verification step and the free tier pull in opposite directions, so treat the reviews with caution. The bit that caught me out was that the boost system matters quite a lot more than the distance radius, so results vary more than you'd think.
