To take the proxy measure suggested above in T198552#4365794 for estimating how many tickets are still affected:
There are currently about 3210 tickets in https://phabricator.wikimedia.org/tag/gamepress/ , compared to around 3470 at 5:09 pm (after the bot had already been slowed down to avoid hitting the rate limit). That would roughly be 90 tickets cleared up per hour, and 35 hours remaining.

@Aklapper : will some protective measures be taken to prevent this mass vandalism in the future? At least, some throttles should be applied (e. g. for mass adding of "Security" tags and for mass creating of tasks with nonsensical task names).

Ad questions

1. What is it?
2. Dead link = https://cs.wikipedia.org/wiki/%C5%A0ablona:Nedostupn%C3%BD_zdroj, archive = doesn't exist
3. Templates in https://cs.wikipedia.org/wiki/Kategorie:%C5%A0ablony:Cita%C4%8Dn%C3%AD are used for citing. https://cs.wikipedia.org/wiki/MediaWiki:Citoid-template-type-map.json is map used by Citoid service. Do you need some specific information?
4. If in citation templates, it's YYYY-MM-DD.

Thanks. It appears though that bullets 4 and 6 are still in English. :-)

I have some answers for your questions:

Added Wikimedia-Incident tag. The incident report already exists...

@Tgr: that looks like sensible approach to me.

Well, the reasoning behind this looks a little bit flawed to me. I can understand the basic idea of a new user right allowing to modify site JS. But:

@ABorbaWMF : Ouch. The previews in your examples are seriously broken. I hope this is not coming into production.

OK, it looks like the initial dust has at least partially settled.

The examples in the second paragraph are not about IPA/pronunciation, these are citation/source related templates. They are all saying something like "dead link" or "source required". Obviously this should be stripped. On cs-wiki these are displayed via the templates which all have a common span class, namely "doplnte-zdroj". But I am not able to find the definition of this class in a local MediaWiki css or js file.

I have some reservations about the "fading" logic. Look at the following previews:

Some more complicated testcases:

@Vachovec1 when I visit https://cs.wikipedia.org/api/rest_v1/page/summary/Kyselina_myristov%C3%A1
it looks like the summary is

<p><b>Kyselina myristová</b> je běžná nasycená mastná kyselina se vzorcem CH<sub>3</sub> <sub>12</sub>COOH. Její soli a estery se nazývají <b>myristáty</b>.</p>

@Jdlrobson : This is probably not resolved yet. Try to get a summary for Kyselina myristová. On my comp, the central group of the formula is omitted from the summary.

that should be fixed in the gadget. The styling introduced by said gadget is very generic. Vachovec1 would you be so kind to flag that to the gadget author(s)?

Well, the gadget definition is here:

MediaWiki:Gadget-HighlightRedirects.css

It's actualy very simple/basic code. So what would you propose?

The en-wiki has something very similar:

MediaWiki:Gadget-DisambiguationLinks.css (author: @kaldari)

I presume that the behaviour would be the same.

I changed the gadget definition from .mw-redirect to a.mw-redirect and it works! The gadget now works in articles and special pages, but not in the previews..

I can see a difference between cswiki and enwiki gadget: .mw- (cs), a.mw- (en). Probably the easiest fix to make both disambiguation and redirect gadgets work only on links in articles, not on spans (as @bearND pointed) in previews.

This can be fixed easily and very quickly on cswiki's side, it is up to developers, if they will fix this in previews as well.

(@Vachovec1) After switching HTML previews on, should we maybe inform Czech Wikipedia community about what happened and how to track bugs right?

It seems there is some collision between the page previews code and "Zvýrazňovat přesměrování" (highlight redirects) gadget now. The redirects in the text extract are now highligted with rose background and overline. See for example previews for:
