And you can’t solve the captcha for some reason? Or it’s just rejecting that you completed it? Also seems like you were able to post a top level reply right here. So it only happens when you reply to someone else?
Are you using any anonymizing services like Tor or something? Those networks are used a ton by scammers, so if you are then it could make our system more likely to flag your page or your comments for either captchas or human review.
