Can’t Find A Big Website With Datasets That I Used Before – Maybe Someone Knows?

I remember I browsed it a year ago quite extensively, but used a different source for my project in the end. Now I don’t remember what it was called and can’t find it anywhere now – can anyone help?

The site had different datasets uploaded by random users, some of them were just, for example, bulks of documents about a particular issue for the last 10 years. No clean data. Maybe it was a bit sketchy, I don’t know. I think it had a red icon/layout and a short name… pretty sure something with a letter “A”
