If there were say as many as 4 dozen of these posts and they all needed to be urgently deleted - that would mean (20+ an extra 45 seconds) 65 seconds max, for each one. That would only be a total of well under an hour's effort to be divided up between whatever number of unknown 'moderators' were involved.

Not really too much time out of one's life to be seen to do a job properly - is it?

There were hundreds of spam posts, and it took a large team of volunteers working collaboratively more than an hour to restore the Mudcat. Asking the entire team to instead spend 4 or 5 hours on this otherwise routine task is an unreasonable expectation on the labor of volunteers who have other things to do in their lives besides documenting their every action for the benefit of one single complainer.
