Reporting abuse and model theft on printables.com
I realize that trying to fight people who "steal" open-source STL files is a losing battle, but there should at least be a mechanism to report egregious offenders, and those who use stolen artwork for contest submissions. The user "IZY_BOI120" is currently spamming the Thanksgiving/Fall contest with models authored by others, and not even bothering to change the filenames. For example, "Large_Spiral_Christmas_Ball.stl" is from https://www.thingiverse.com/thing:5129377 , and "Bon_Garcon_BowTie-V2.stl" is, unsurprisingly, by a user named "Bon Garcon" here: https://www.thingiverse.com/thing:543117 .

There is a reporting mechanism. Has been for ages and ages. 3 dots icon on a models page, click on it and one of the options is Report.

Not at all saying that's what's happened here (what you described sounds like wholesale theft all right), but I have noted frequently the same models posted under different usernames here and at Thingiverse, but if you spend a little time looking at profiles and the rest of their models, it's clearly the same user. A better practice might be to attempt to contact the user who you think is a victim of theft, and let them handle the reporting, if any is necessary.
