Yes, it give higher leveled autojoiners too, but 2/3 are level 0 or 1 because you need only 1 GA, a freebie that isn't set to free is enough, ro reach level 1. For level 2 are around 5 GAs needed (one GA that is cv optimized is, of course, enough too but let us work with numbers without such optimizations). So each one that is a few months active on sg can reach level 2 without a problem for maybe $2 - $4 (without optimizing, with optimizing for free or max. 35 cents).

if there is a way I can find these guys and report let me know.

Very easy for you with your GAs.
At least for the stupid autojoiners with activated thanks script.
Note the ones that write always the same thanks message, put all the GA links they appear with their thanks spam to it. And then send it as report.
If you use ESGST, you can check their entries and posted messages with the exact seconds. That help a lot to see if someone are able to write 5x thanks and enter 5 GAs in 1 second or such unrealistic lightspeed that no human are able to reach. If you use ESGST add screenshots of the exact comments and entries times to the reports.

That, of course, don't prevent the entries of the, a bit, smarter autojoiners without activated thanks script. But each bit help :o)
