That's probably why the "reputation" of the coordinator matters, especially if the individual who bootstrapped it is an anonymous. But it would probably help if he/she is a known entity in the community.
How many times do I have to repeat this: You do not trust coordinators, so there's no reputation required.
I have a question, what if the entity that started the coordinator started bootstrapping it by using different wallets, pretending they're owned by different individuals, but with honest intentions?
Then they would be spending an enormous amount in fees to only create superficial results. Whether the intention is honest or not, this behavior is indistinguishable from a Sybil attack.
