Free tier IP-level block: "detected abusive traffic" on home network — expiry / review? #56853

Description

Since 2026-10-18 ~15:13 UTC, every free-tier request from my home network fails at the IP level with the "detected abusive traffic" error below. The same account and app work fine when I tether through a mobile hotspot, so the block is scoped to my home IP, not my account.

Context: previously, a local learning plugin (claude-smart) used opencode run through a local CLI bridge to make small automated extraction calls against the free tier. That automation was very likely what triggered the flag, and it was my mistake to point it at the free tier. I have now stopped that automation completely and rerouted it to a third-party API (Zhipu GLM-4.5-Flash). It no longer touches the free tier at all, and I will not point automation at the free tier again.

Error

AI.Error.Authentication: OpenCode's free models aren't available from your current network
because we've detected abusive traffic from this IP address. This isn't related to your
account. If you're on a VPN or proxy, turn it off and try again, or subscribe to OpenCode Go
at https://opencode.ai/go

Steps to reproduce

1. On my home network (China Mobile residential, no VPN/proxy active):

   opencode run --agent plan --model opencode/deepseek-v4.1-flash-free "Reply with exactly: PING"
   

2. Observe 403 FreeTierError "abusive traffic" (CLI). The desktop app shows the same error on all free models.
3. Tether through a mobile hotspot with the same account and repeat → free tier works normally.

Timeline (UTC)

• 2026-10-18 15:13–16:16 — 98 "Failed to drain Session" log entries with the error above (desktop app sessions).
• 2026-10-18 16:42, 16:46 — same error from a fresh CLI run after switching back to the home network (session IDs ses_eb01b1da8ffetMixmgjFUFIsqH, ses_eb1a62987ffeGG6dLRsmK8iuJr).
• 2026-10-18 ~16:57 — still reproducible; the block has persisted for ~2 hours so far.

Questions / request

1. Does this IP-level flag expire automatically? If so, roughly how long does it take?
2. If it does not expire, could it be reviewed and unblocked? (Similar to OpenCode's free tier can only be used from within OpenCode. Download it at https://opencode.ai and keep building. #55483, where the same question is still unanswered.)
3. Any guidance on what counts as "abusive" for CLI automation would be appreciated, so I can avoid it in the future.
