Disagree. I get to delete these things practically every night and I am sorry that you feel so inconvenienced. They don't come on a regular schedule. Sometimes they come in waves. Sometimes in dribs and drabs. We have three or four mods who regularly participate in cleaning them out.
Overall, I think that the grammar quality isn't that horrible. I don't think there is any special purpose to the style.
Some people will say that they are bot prepared. I don't think that is true. If they were, I would expect the quality to go up but the variety to go down.

Okay, I have a serious question about all of these scam threads trying to sell gummies and pills. Clearly, there's no way the site is able (or willing) to stop these threads, so we'll just have to tolerate them.
The grammar and content of these scam posts are so insanely illogical that it's obvious these scammers are making the posts stupidly illogical on purpose. No human on the planet could be *that* bad at English grammar, even if he didn't know any English.
So my question is, why are they doing this? My only guess is that maybe they're trying to construct the text to evade automatic spam filters. Anyone agree or have any other ideas why they do this?
