Hello to the fediverse !
If you are admin of a Mastodon instance, you should check if IP from the bloc 43.160.0.0/12 (precisely IPs in the ranges 43.172.194 to 198 and 43.173.173 to 194)
are asking for A LOT of pages and consuming a lot of CPU / Bandwidth.
It's a malicious bot that harvest the fediverse by tags, feel free to bloc it 😉
