@martijn thats probably you having too much ieji stuff open😅. the anti ddos config I use is pretty damn aggressive, just a couple of ctrl+shift+r gets you blocked for a short time. Shouldn't be noticeable in typical usage. Me setting everyones IP to 127.0.0.1 effectively removes mastodons own rate limiting(for debug reasons on localhost), so I had to do it on webserver level instead.
