Any suggestions how to deal with him? Aren’t there any moderator tools to block his IP for a day or two? (it is really annoying that he can just create a new account immediately)

He even got some up-votes, I guess he has already created a new account…

Repeat offender: someone who is convinced (by RH crankery) that they have found a mistake in Cauchy's theorem from complex analysis. http://mathoverflow.net/questions/134594/not-analytic-riemann-zeta-function I think this warrants immediate suspension.

I hesitate to continue this discussion here, but personally I would be very hesitant to undelete an answer an active user deleted (you might preserve the one and loose all the potential future ones in the process...). Also, AFAIK, moderators could anyway have undeleted them all along, and +10k users can see them (and the fact that it happens relatively conviently in a list). So I do not see why migration changes much anything, and even if it would I would be still against such undeletion activities.

After migration, we will be able to undelete answers (3 votes). It would help if Scott or the other moderators provided us with a list of answers that have been self-deleted and yet seem worth preserving.

@Scott, good point, Lavender Honey/Powerpuff, after two years, deleted at http://mathoverflow.net/questions/23943/can-a-positive-binary-quadratic-form-represent-14-consecutive-numbers . I was new at this in 2010, these days I would accept an answer that says "The best answer uses conjecture X, here's why you cannot expect much progress without it."

@Scott: thanks for the explanation. That's too bad. I can sympathize in a small way, but if I were to give advice to LH, I'd just remind him/her of how inherently silly and even absurd are many voting and answer-acceptance patterns (so: don't take it seriously). Even some high-rep users can be very, very silly people. :-)

@Scott Carnahan: thank you for the explanation so I take it this is meant as an encouragement of the activity of this thread (i.e., deletions without much discussion in clear case) as opposed to François G. Dorais being against this thread, which was rather my initial reading.

Scott Carnahan comments on "Crank post to flag as spam" (22629)

2013-06-22T09:11:52-07:00

@Todd: Lavender Honey has exhibited a strong tendency to delete any answers that are not accepted, even if they are really good and suggest a substantial investment of effort. Sometimes the deletion happens within a few days, and sometimes it takes a few years.

In general, if you are engaged in a long conversation in MO that doesn't seem to move forward, you may want to consider the title of this thread before wasting much more of your time.

2013-06-22T08:47:41-07:00

This is off-topic, but looking at the page quid linked to three comments ago, I have a hard time understanding why Lavender Honey deleted his/her apparently very well-received answer.

But I disagree with you that the post was any less spammy. The only difference I see is that he did not have a preprint handy to advertise.

@Andy: am in a rush, but quickly

I think AL's answer was misguided, but not as "spammy" as the posts being discussed here, nor as obnoxious as the efforts of such luminaries as Ron L Winger, WM, and the guy who decided to insult me using the code of some kind of US visa form (slight misfire there, I fear; Trudeau would not have been impressed)
I think BC's comments are worth reading, but so are the comments by e.g. PLC. I don't like the idea of comments as gospel
I disagree that the answer needs more downvotes. It was, I believe, meant in good faith. There seems no sense piling on, we are all capable of finding a pinata should the urge arise.
