Well I didn't see the request but usually I'd ban for 25d.
Does it really matter if it's 25 or 30 days, especially since you get only banned from 1 room? Not in my opinion. Once we get going with the global bans, then it will make a difference. The other things you mentioned are irrelevant when banning someone, but can make a difference when applying for an unban.
Anyways, like I said you should make posts like these to the unban section. We don't have the authority to unban people, or overrule another mod's decision, unless a mistake was made, which in this case was not.
