They're getting too long. I was one on there that was 728 characters long and hogged up the whole hub screen (It was mine) and many others which, while not as long, were equally annoying.

I'd like to suggest either having the hub listing cut off the end of names that are too long (perhaps over 50 characters or so), or maybe just having the hub not allow names that are too long to appear on the listing.

It just seems like an open avenue for abuse and I've seen it happen on more than one the occasion (the one of which was my own).
