So the fedi spammer is now just sending an image of a link to his discord instead of a wall of chinese glyphs.
This makes even server-wide post filtering ineffective.
The only real solution is to limit/block insufficiently administered servers that allow the abusive behavior (automated account registration and spamming).
OCR + other tricks could help in this specific instance.
The spammer has made the flaws in Mastodon's technical moderation capabilities quite apparent. Needs spamassassin.
