@hugo Thank you for this! We had the same issue with mstdn.social on the exact same day as mastodon.social but fort i my response was in time to not get 'banned'.
I have done many scans since this issue but never found anything else than the one account with a "ping IP" in the bio! I've spend a load of time getting us from all VirusTotal related sites since many just copy paste the result :sad_cat:
@stux Thank you so much for sharing.
How did you mstdn.social out of VirusTotal? I could do it on CRDF Threat Center but don't know how I can do it on VirusTotal.
