Vandalism/removal of legit listings on Kommunlane chtyvo napysane kryvo, as well as on my personal page

In what now happens pretty much yearly both my personal page and the page of my feature film in production for a long time again got vandalized. I would have suspected good intentions due to "believability" of both but it is really, really easy to guess the motivation behind the removal: to drastically reduce the STARmeter (one of the features I ironically don't care about). In case of my page Bohemian Rhapsody (2018) was removed from "Additional crew", something that I've reuploaded with proofs at least once at this point (not counting several declines) and will need to do all over again. I anyhow have the proofs at arms length just in case, so this is already reinstated, thankfully. 

In case of Kommunalne chtyvo napysane kryvo there is a periodical purge of people with what could be called celebrity status. From what I was able to assess (I have an alphabetical cast list specifically for this purpose as well as for future end credits) Clint Basinger, Josh Becker, Christopher J. Dinnan, Paul Harris, Haddaway, Oleksandr Sydorenko, Ihor Kondratiuk, Valeriy Chiglyaev, James Rolfe and Krzysztof Zanussi were all removed. In cases of some of those I will consider it a good sign to proceed with their cameos since one was stuck in a legal uncertainty (agreement was achieved years ago and I am not sure whether it still stands) and three were listed as "(rumored)" for ages since they agreed for cameos but still haven't filmed them. I've noticed that adding anyone before material was filmed to no budget projects like this 'jinxes' it a bit, so next time they will be re-added there will be no "rumored" status. That said, at least seven people out of those have wrapped cameos in the movie filmed or recorded (in case of voice appearances) in 2015-2018.  Decided to combine the re-addition with a long overdue update of the cast (#220212-235019-008000).   

Not to be too bitter about this situtation, but... How on Earth this happens every year and it is re-adding people through the title scorecard that is much harder than seemingly removing the cast on the long established title that's been on IMDb for years? Granted, the title is in production (which adds another layer of vandalism when someone attaches a phony release date and then attempts to review bomb the movie, failing miserably), but I wonder whether it is vibisly, internally in the system, that a company with a scorecard is attached to the title.

Edit: I was able to reinstate most of those but encountered an oddity of a problem in #220212-235019-008000. Two listings were approved, but then somehow bounced back to declined despite appearing on the title already. 

First time seeing this. Reuploading the two credits through scorecard, again (#220214-202019-960000).

Somehow that reverse-decline thing also happened with my Bohemian Rhapsody (2018) listing (#220212-223426-243000), too.

Is someone reporting those updates somehow, despited them already being approved?.. If so (and especially if it is in broken English) that is very likely the same person who is removing my listings for years at that point. 

Overall, it gives me much more anxiety over updates. Normally if I see "approved" or "declined" I go from there. If something could be declined after it was approved now that's probably logical and useful on some level, but I will now habitually return to every single edit to see whether something had changed which is somewhat less efficient.
