I'm pretty sure this is a translation issue, and he must have meant his post history.

Cool! So Guess R20231030 is Ratimov's new name

I checked this list, and those topics have been restored:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34.
That includes some of my own (Merited) posts in topics that weren't self-moderated, and Ratimov indeed should indeed not have any power over those.

I didn't realize until now that also Mods deleted topics with other posts. That's quite a big mistake.
