I'm sure anyone ordering from a website knows the increased risk involved.
They're probably popular with the reddit/tiktok community due to easy of ordering (website) and low prices with availability. People there also don't care about test results and are more focused stuff like on speed of delivery and freebies.
It reminds me of QSC and SSA, they blew up on social media and got raided. In any case, it's always good to have a vendor willing to absorb the LE and public attention. Someone has to do it for the good of the community.
On the plus side, with enough volume from reddit/tiktok, vendors can stop posting here and save money on testing (Same thing is happening with the CN vendors now -- they got enough traffic to the point they stopped testing and posting).
