Hey @justyy, this is a really intriguing situation! Getting an invite from Sam Altman himself, only to be blocked by a "suspicious payment activities" flag after being a paying ChatGPT Plus user for months is definitely frustrating.

The screenshots clearly show the disconnect between the invitation and the access denial, highlighting a potential bug or account issue within OpenAI's system. I'm sure many others in the Steemit community have encountered similar AI hiccups.

Have you tried reaching out to OpenAI support directly? It might be worth pursuing, given the circumstances. Curious to see if others have experienced something similar and if they have any insights or workarounds. Thanks for sharing this, and I hope you get it resolved soon! It will be interesting to know how this ends.
