Nope, why would you? :3

Honestly, there doesn't seem to be any reason not to make an exception check for users that entered the giveaway when it was active, or especially for the winner. As far as filtering problematic commenters goes, that's what blacklists [and site suspensions] are for. There's no gain to allowing the fairly frequent closing and reformation many groups go through to affect subsequent commenting, and seemingly no downside [other than focusing site development resources toward it] to arranging things so as to bypass that.

you just need to be promoted to support.

You mean you can't comment/delete your comments on a giveaway for a group you left? It's not really a bug, it makes some sense really. If a user is being a little shit and gets kicked, I doubt that the user would appreciate the user going through group giveaways saying "INVIET ME AGIAN PLS".

How common is this use case though? I guess you could always comment on another giveaway by the same user, or on his steam profile.

Couldn't you just message the creator directly and thank them that way?

I understand the sentiment and I wish it was possible. Annoying to go through the persons gibs to find a random public one just to thanks for a game you just played :/.

feature

which a user is no longer a member

how does one un-become a member here? you mean once they are inactive? banned? or suspended? or am i missing something?
