I’m just responding to your last sentence: why would you go out of your way to say it is reasonable to block the account rather than the project?

I can understand locking the account just as the “lazy default” but I would not call it in any way reasonable - but you did, so I’m curious.

If that is reasonable, what would you consider unreasonable?

(Because to me, the obviously reasonable thing to do would be to block the project and not his entire account.)

Just because it's their right to conduct this way, doesn't mean it's not everyone elses exactly equal right to judge that and avoid.
