Person claiming numerous credits for jobs they didn't do

User is very cleverly claiming credit for positions that are less easily able to be tracked, but the credits don't make sense in aggregate. I first noticed them because they claimed to work as an "additional still photographer" for a unit in a location we never filmed in, and had the credit deleted. Then they successfully submitted a credit after that for the same film as "crane technician trainee", even though we had no such position, and that work would have been done on a different continent from the first location they claimed to work in.

When I checked their IMDb page, it has a handful of producer credits that may be legit (hard to tell; there is also a 12 year gap), but virtually all of the camera department credits are highly suspect. They're mainly additional stills or second unit, or additional stills second unit, but it doesn't pass the smell test because they are all over the map, literally. People do sometimes get flown out, but it's pretty rare for stills photographers, and more or less never for day players. I don't find it credible that this person did day playing in the past year or so in New York, Atlanta, Los Angeles, London, and Sydney - especially given that I know for a fact that at least two of their claimed credits are completely made up. And again, there's no plausible career progression - they have two credits in the late 2000's, then suddenly emerge in 2022 working on major projects (with literally a dozen in the upcoming section). Finally, I checked the union membership for my local, and this person is not a member, which means they literally would not have ever been allowed to work on most of the US shows.

It doesn't pass the smell test.

Is there anything that can be done to fix this and ensure that it doesn't repeat? I would like to avoid seeing this person claim more and more ridiculous credits on the shows I worked on - it's an insult to the hard work of myself and my fellow crew members who DID do the hard work.
