not defending them per se, but i haven't really seen much more around the internet about them being shonky
There is plenty if you do a bit of searching. There's a reason they are banned from M3Forum, which arguably would have been their largest market. Aside from ***********(which is little more than a subsidiary of HPF and Gintanni via Sticky), they aren't held in high regard on any forum.
