Though it seems a bit odd but on a commons perspective it is also a normal procedure. Commons has a huge issue with people finding images online and then uploading them as their own work, so regular contributors on commons can sometimes be overzealous in making sure that people actually have the right to release what they are releasing. That is where the OTRS system comes in. Rather than complaining to the process could you please for once think that this is your project too and everyone in this together?

We, from WLM Bangladesh team have created a work-board/list for such users who have problem with metadata, previously published same image on other media to make sure that they are actually own the copyright. we even created a hand book for reviewers explaining what to look during the review (https://commons.wikimedia.org/wiki/User:NahidSultan/WLM). So, every reviewer check for those mistakes when reviewing an image then if they found such problematic user they immediately contact them via email or talk page and list them on https://commons.wikimedia.org/wiki/User:NahidSultan/WLM/possible_copyright_problem.  It works for us.

Best,
