One line too many?
"Additionally, if you are a moderator, it allows you to ban for an extra 2 hours on any chat you are a moderator."
The sentence doesn't really seem to fit in between the lines and the overall wording is off. I assume it's talking about the 8mod power, though it itself isn't mentioned anywhere near the given sentence.
My suggestion would be to remove the line completely and improve the following line:
A moderators maximum ban time is: 0-99 hours. (0 = forever).
