As Speaker, the only thing Lappy can do is apply changes decided by the Legislature. Furthermore, these changes must usually be made through the ACP only. There are some exceptions, such as adding emoticons, etc. The main point of the Legislature is to make new ideas.
Wee obviously didn't make those posts to affend Josh, since Josh wasn't at the forum at that time. Josh may have made his posts to offend wee, however. Anyways, Lappy won't be able to moderate this stuff. He could try starting a movement to get someone banned, though... or fined... but that would take a year, and it would be a waste of time.
