Well, you should firstly know that the forum does not 'endorse' altcoins nor focuses on them (this lowers the chance of a possible change a bit). Some of us even consider it just another trashcan section (e.g. me). However, I also dislike ponzi's and they were causing a a similar issue in Bitcoin related sections before they got a separate section. It might be good to pull statistics from page 1 and 2 (e.g. X amount of threads out of Y are ponzis).
Haha I kinda agree with the trashcan section with the exception of a few promising alts with legit new innovation. I hesitated before starting this thread too, however as meta includes the whole forum in general i decided to just post it anyways. Last I counted yesterday, 32 of the 50 threads on page one were ponzis/scams/investorbased games.
To be honest if I was the mod of altcoins I would simply delete all of them "investor games", but with freedom of speech and free will and how fools are bound to lose their money one way or the other, they are bound to exist. But as someone who was looking for a some altcoin exchanges to sell some coins I was kinda pissed having to crawl through all that bullshit before finding something legit, so I was thinking I am definitely not the only one.
But oh well, alas the final decision belongs to mprep who mods the altcoins marketplace.
