Temporary blacklist/mute option

Would it be possible to add a temporary option to the blacklist for when you're tired of hearing someone but don't think they really deserve being put on there and forgotten about? A lot of times I wander into a zone and get bombarded with FC promotion spam, emote spam, etc., and I'd really rather not block out every chat channel to avoid it.

It would be nice to just sort of mute someone for 1 hour/1 day/1 week/etc. just to avoid seeing them in chat logs without having to remember to remove them when they get lumped in with people I genuinely never want to see speak again and gil sellers and I forget who they are.

If not, could we have an option to make a note of why we blacklisted someone so we can remember?
