Link-Preview on IceCast Server takes too long
I own a really small webradio and running all the servers on my own.
So I also run an IceCast2 server that is used for the webradio stream itself.
Some of our listeners seems to use Pleroma to promote my webraddio.
So every now and then a bunch of about 50, sometimes 100 sometimes up to 200 Pleroma bots floods my IceCast Server
that much that normal listeners cannot connect to it, due to a limitation of max. 200 listeners.
Those bots stay for several seconds. Sometimes for about 2 minutes.
During this time no new real listeners can connect.
Even worse, I need to pay for this traffic to the german GEMA and GVL Rightholders.
For traffic that isn't even heared.
Mastodon had this problem as well a few months ago. But since one of the newer versions this is gone.
I do not know why... But suddenly Pleroma Bots appeared...
Maybe you can dedect if the link is a MP3 Stream and stop trying to preview it?
