Put bluntly, the rules that OSM has in place around imports are there for a reason - to stop well-meaning but poor quality imports happening.
If anyone sees an example of imports happening that aren’t following the rules please do report them to the DWG. We will always try and work with importers who don’t seem to understand what they are doing (see e.g. here) rather than just “revert all and ban everyone” but sometimes it is necessary to nip problems in the bud before they become more serious. We have in the past blocked the creators of task manager tasks until they have complied with the rules.
However, I suspect that a number of the “imports” that you found by searching aren’t really imports. Taking just the first listed one as an example (unfortunately you have to login to HOT’s private server to see that) it is essentially just “mapping from aerial imagery” - it doesn’t seem to be an import and doesn’t seem in any way problematic.
