Repeated application of \<sup\> and \<big\> can be used to cause content to appear outside of the post box

Example: This was in wrong place.

```plaintext
Example: <sup><big><sup><big><sup><big><sup><big><sup><big><sup><big><sup><big><sup><big><sup><big><sup><big><sup><big>This was in wrong place.

```

I don’t know that we entirely care about this.. abuse can be classified as “don’t use standard formatting to do annoying things”.

Under penalty of suspension, etc.

Not for this report, I mean if people were doing this just to be annoying all the time.
