@Ramhound Actually, that's precisely what I won't be doing ;-) I said "I'll just action any Review Queue item for the user as per normal".
The part that might be a little confusing is "but not attempt any further mentoring". So, just to explain, very occasionally (I think I've done it twice or so), if I notice a systematic trend of problem suggested edits I will contact the user outside the queue (either via chat or via a comment) to further explain in detail/supply supporting links.
With this particular user, while I was in the middle of a Reject and Edit on a trivial, incorrect suggested edit (on a newly posted question, it used backticks to highlight a non-code, non-command ordinary part of a sentence, and used bold to highlight an already capitalised program name), the OP approved the edit.
I shrugged my shoulders and went on to the next item in the queue. This happened to be by the same user, and while it was a minor improvement (it fixed the same word mispelled twice, capitalised the start of all three sentences, split the four-line single paragrah into two, and trivially tweaked the title), it also removed the only critical tag (out of two total tags), didn't fix the egregious grammatical errors, and used bold formatting to highlight four effectively random sections of text.
So I did another quick, draft Reject and Edit (so the OP wouldn't have time to approved the suggested edit from under me ;-) ), and edited it outside the queue, to polish it off. Unbeknownst to me at the time, even though the two edits were only two minutes (and two seconds) apart, they ended up as separate edits both with same repeated extensive message to the user in the edit summary.
(I've now worked out that this was most likely due to the moderator who stepped in and rejected the edit plus closed the question whilst I was in the middle of the Reject and Edit. There seems to be a bug involve though, as the sequence of event seems to have been 1) I started the Reject and Edit; 2) @ X:48:20 the Mod rejected the edit; 3) @ X:49:00 the Mod closed the question; 4) @ X:50:36 my Reject and Edit is applied; 5) @ X:52:38 my second, normal edit is applied as a separate edit)
This would normally have been the end of my involvement, except I decided to check out the user's profile, and found a third suggested edit, essentially just an abuse of bold and backtick formatting, which had been approved by the OP. Since there were now three edits in the space of ten minutes, all of which should have been rejected but two had been forced through by the OP, plus the user having just started suggesting edits after a two year break, I decided to contact them directly.
So, I rolled back the first suggested edit, re-edited the third one to show what a good edit looked like, then contacted the user explaining what I'd done and why, but leaving any further discussion up to them.
So, in summary, if I see an item in the review queue by this particular user, I will treat is exactly as I would if it were by any other user. If I see a suggested edit repeating the same issues I tried to address, I won't contact the user directly outside the queue again, but instead, I'll bring the issue up with a Moderator. (Which is what I would most likely also do for any other user anyway - that or just simply drop the issue.)
Unfortunately due to some technical issues, this took a bit more than expected to be conveyed. Coupled with the fact that, according to the edit summaries by the user, the two approved suggested edits could have been more extensive, but each clashed with a previous edit repectively, and the previously mentioned repeated edit summary on the one post, I can see how this could piss somebody off.
