Yeah, I would not download if it wasn’t strictly curated by trusted admins. But possibly the site could be opened up to trusted moderators to share the burden.
For instance, I have an elegant themes account. I could (if had the time) monitor those themes and plugins.
BTW, I am curious if the cheapskates that are downloading are donating to the website?
I assume this is very time consuming and your time needs to be paid for somehow, unless you’re ultra-rich and doing this strictly for philanthropic reasons.
