Lemmy World under DDOS attack

And by by executing them by the thousand a minute you can overload the database server.
So who is attacking us? One thing that is clear is that those responsible of these attacks know the ins and outs of Lemmy. They know which database requests are the most taxing and they are always quick to find another as soon as we close one off. That’s one of the only things we know for sure about our attackers. Being the biggest instance and having defederated with a couple of instances has made us a target. ..."
Why? Maybe because of this?
