Another spammer

User:PetruJunel is a spammer, see his contribution. --Boris Tsirelson 14:25, 7 December 2011 (CET)

Also User:Bhseo542 is a spammer. --Boris Tsirelson 17:12, 13 December 2011 (CET)

Is User:SteinerDigby2706 a spammer? His page Ultimate Coders Coding Reference, containing a link to "Stack Overflow", is hardly relevant. "Math Overflow" could be tangentially relevant, but not "Stack Overflow".

Oops... "Stack overflow" is insisting: User:MickReeves396. --Boris Tsirelson 17:58, 17 December 2011 (CET)

Still alive... --Boris Tsirelson 20:01, 17 December 2011 (CET)

Now User:LafayettePleasants1397 with his Parking Games. --Boris Tsirelson 07:46, 21 December 2011 (CET)

Now User:DevoraVandenhoff2894 and User:MaegthBreese1139 (I guess, these are really a single human) with their Fishing Games. --Boris Tsirelson 21:44, 24 December 2011 (CET)

But User:MaegthBreese1139 is still alive? --Boris Tsirelson 07:41, 25 December 2011 (CET)

Now User:EricaMorgan, see this diff. --Boris Tsirelson 20:44, 27 December 2011 (CET)

Now User:Kaixinde with User talk:Kaixinde, User talk:Kaixindea, User talk:Kaixindeab, User talk:Kaixindeabc, User talk:Kaixindeabcd ! --Boris Tsirelson 07:39, 29 December 2011 (CET)

Now User:Chrisschmidt30. --Boris Tsirelson 21:28, 6 January 2012 (CET)

Now User:Hybbike1. --Boris Tsirelson 08:12, 8 January 2012 (CET)

Now User:BeverleyPye574. Strangely enough, he advertises Microsoft. --Boris Tsirelson 12:49, 12 January 2012 (CET)

Now User:RowenaKirkland, see this diff. --Boris Tsirelson 14:39, 13 January 2012 (CET)

This site sure seems to attract a lot of spambots!--Colonel Sanders 15:26, 13 January 2012 (CET)

Now User:GreeceEFT. --Boris Tsirelson 08:06, 14 January 2012 (CET)

Now User:Hawksysgt. Account created at 12:51, 17 December 2011. I wonder, who are the other (more than 100) inactive users. Sleeping spammer bots? --Boris Tsirelson 13:02, 14 January 2012 (CET)

Also User:Proamuntz. --Boris Tsirelson 13:35, 14 January 2012 (CET)

Could we also have such a meeting place?

Something similar to this would be useful. (Or like this. But please, not like this.) And by the way, did you see this topic? An EoM-relevant quote from there follows. --Boris Tsirelson 15:05, 13 December 2011 (CET)

"I am the product manager at Springer responsible for managing the technical implementation of the new EOM wiki. I have adapted the citation template documentation for the template:SpringerEOM to use the proper naming convention for the new site. I will be closely watching the site's incoming traffic from WP and updating the ids of WP citations that used the template so that their link-outs will resolve to not only the correct article in the new EOM wiki, but to the version of the article that is identical to the version previously hosted at eom.springer.de.--Nbrothers (talk) 16:13, 30 November 2011 (UTC)"

Categories

Something is wrong, I guess; we have now both Category:Dynamical Systems and Ordinary Differential Equation and Category:Dynamical Systems and Ordinary Differential Equations. :-)

Thanks. I guess I fixed this.--Ulf Rehmann 22:43, 9 January 2012 (CET)

And by the way: when all first chars are uppercase and when they are not? --Boris Tsirelson 22:23, 9 January 2012 (CET)

Aha, I was careless here. What is the Wikipedia convention? What happens if I rename a category? Will the renameing shift all the entries in its files?--Ulf Rehmann 22:43, 9 January 2012 (CET)

On WP they are generally lowercase; example. No, I am afraid changes in all pages need to be made by hand. And by the way, also replacement of "unofficial" templates to "official" ones (when ready) will be made by hand. Unless we'll create corresponding bots, which is feasible but not so easy (as any programming). --Boris Tsirelson 22:47, 9 January 2012 (CET)

Ok. I'l fix the cases issues. Concerning the templates we'll see later. I guess when programming bots one needs admin access to the machine where the wikimedia is installed? That I don't have (otherwise we'd already have the ParserFunctions ext.... --Ulf Rehmann 23:32, 9 January 2012 (CET)

You mean, the root access. No. Not even admin rights on the wiki. I did it once on Wikipedia, being just a plain user. --Boris Tsirelson 06:47, 10 January 2012 (CET)

But for organizational reasons bots are best run from separate "bot" accounts. This link may be helpful. --Peter Schmitt 15:16, 10 January 2012 (CET)

Thanks for your hints. I did find perl based bot which works.--Ulf Rehmann 12:25, 11 January 2012 (CET)

Keeping spammers away

It could help, to provide an account only after asking a math question and getting the right answer. The question should be replaced from time to time. Here is one, for example. :-)

Calculate the area of the set of points $(x,y)\in\R^2$ satisfying \[ \Big( \frac{x}{\sqrt{15}-1} \Big)^2 + \Big( \frac{y}{\sqrt{15}+1} \Big)^2 \le \frac3\pi \, . \] --Boris Tsirelson 11:12, 14 January 2012 (CET)

And we should not underestimate the problem. See e.g. [1], [2]. --Boris Tsirelson 13:27, 14 January 2012 (CET)
