@HighlyIrregular As far as I am concerned, just flagging the post as spam is enough. Editing is not necessary.

But I'm not sure if I understood EnergyNumbers correctly.

@EnergyNumbers Were you saying with your last lines that you want to keep the valid questions of the spammer even if there will never be any response from the asker? And what about the account then?

If we don't delete the account, we do risk spam answers and comments (that's the behavior I saw the first time when we only edited out the spam link from the question).
