Already in 2015, Emily Taylor warned [1] that ICANN could become the Internet's FIFA -- a small organization with great power that doesn't answer to any government. Here we are. A private company run by former ICANN people will be given the right to collect massive rent from a locked-in client base on a public resource.
For my small wiki, refusing all submissions with external links eliminated virtually all spam. Yes, it's drastic, but in my case external links were not essential. I still use ReCaptcha to cut down on spam account signups.
Agreed – looks like a fantastic product!
Seconding the question about MySQL support. I use MySQL for everything. I don't want to add extra gigs of RAM to my VPS just to run an instance of PostgreSQL for Commento. Postgres is much slower than MySQL in simple applications and uses a lot more memory per connection. MySQL is also more popular and more people know how to use it and tune it properly. Postgres is probably more stable, but I don't care about that in a commenting app.
There's economic research that shows it's more efficient to regulate (in some sense, "blame") the lenders, because borrowers are often desperate. When you're desperate, you have reduced capacity to objectively judge the consequences of borrowing and are also less sensitive to "blaming", potential penalties for overborrowing, etc.
From this perspective, putting all the blame on borrowers while exonerating the banks is exactly the opposite of what we should be doing as a society, if we want to avoid another debt bubble.
