a bit more context might help drawing out a solution to your problem
Where are you trying to post? Here on the forums? on Tapas main website? specifics help narrow it down
What was the content of your post?
Other factors that might be at play are that your account (if we're talking here on the forums) is still relatively new so the systems automatic moderation could be flagging things it deems suspicious even if there isn't any wrongdoing. But again without more details as to what you were trying to post or where it becomes a bit tougher to narrow down the list of what went wrong 🤷
