#InstanceAnnouncement Coordinated Potential Bot Network Suspended

We have detected and suspended 5 coordinated bot accounts today.

Indicators of Compromise:

• Content consists of semantically incoherent English text generated by LLM — no direct harm observed, but likely used for account seasoning and filter evasion
• All 5 accounts registered between 2026-03-18 17:52 and 2026-03-19 23:50
• Profiles contain a single English sentence + emoji, or several meaningless English phrases
• All connection IPs belong to Cloudflare proxy ranges
• Registrant domains include disposable email services and high-risk domains

Actions Taken:
Accounts suspended (all IPs verified as Cloudflare IPs — no user privacy has been compromised):
@iwutyp 162.159.XXX.XX
@PhyllisReynolds 172.70.XXX.XXX
@ezob 104.23.XXX.XX
@uhux_xudym 104.23.XXX.XX
@Ethel_Robinson 172.68.XXX.XXX

Email domains blocked:
tmail.lt, maxseeding.vn, dqsbf.blema.io.vn, sphinx.launders.money, kimora.space

Notes:
Registration had previously been set to open in order to simplify the sign-up process. We are now enabling "Require approval" + "Require a reason to join".
If you spot accounts with similar characteristics, or matching email domains/IPs, please report them.
This instance does not welcome malicious or unmoderated bots.
