@penguin @NotoriousDOG @IgnorantHussy @matty @mint @Soy_Magnus Takes very little time; Pleroma and Mastodon both let you upload blocklists as CSVs. So, here's a CSV with all the nicecrew.digital users that FSE knows about. (There are probably more.) Export your current blocklist (if you have one and you care about its contents), then upload this to replace it. 30 seconds. You can do this from any instance that hasn't blocked nicecrew.digital and vice versa.

If you have another 30 seconds, after their bot stops spamming, you can upload a blank file to replace it, and their bot will spam the unblock messages. You can repeat this process as many times as you like. Anyone can stand up an instance, manufacture users, and upload this blocklist for each of those users. (If you know enough Elixir to send the block messages manually, you can do that, too.) You could even register on their instance and do it, it'll go even faster without the federation overhead, but I think they require admin approval.

But this one file, anyone can upload it as their blocklist from anywhere and immediately activate nicecrew.digital's spam-cannon.
