Post making contest 1.0

Okay I'm late to the game but I'm willing to play. I'm gonna solve your secret post rules Sruix you can bet on it.

This post violates rules 1, 2, 3 and 4.

We had two posts that separately didn't violate Rule 5, but when combined into one post they did.

However, the longest post didn't violate Rule 5. So it's not simply length.

Something about number of letters/characters, maybe? Like, the total number has to be odd or a multiple of 3 or something.

This post violates rules 1, 2, 4 and 5.
