I never went through the verification process so I don't know how it works. But I see you requested verification March 1 and the forum admin stated all accounts were verified on March 3. So I agree your should be fine. And the messages about posts being
flagged as spam (for accounts needing verification) only seemed to arise in the last 2 months or so, a message that makes no sense and only confuses. I also note that your post still does not show as reported abusive.
Perhaps the best step now is to email fissues [at] microsoft [dot] com with details and a link to your profile. The forum admins at that address can investigate. They can check if your account is verified and see if the post you linked was ever reported
abusive, by the spam filter or some other process, and who or what process removed the abusive flag. Maybe they slipped up and did not verify your account.
Fighting spam in the forums is a constant battle, and the admins have done something in that last year to greatly reduce the amount of spam. But they need to constantly tweak the system to keep ahead of the spammers. False positives still happen, the spam
filter is not flawless, and the admins can slip up.
