Aside from the Lobby, most rooms are very inactive, unless you're digging into those that have age restrictions where, if you're in the younger pool, are fool of creeps that are clearly trying their luck with different aliases, or if you're in the older pool, are not the best choice for SFW conversations. It's almost as if being 21+ means you MUST be into naughty chats. Gross.
There are prejudiced people here, as the internet is wont to host, but Y99 either lacks moderators or has a severe case of "if I ignore it, it doesn't exist" problem with its staff members. And by prejudiced, I don't mean personal beef. This is literally religion, race and political discourse that should have no place in a chatroom that isn't dedicated to social issue topics.
The interface looks like it would be better off as a mobile app. Right now, it looks underdeveloped, and has been for a year at least now. Buying premium at a minimum of $1 a month gives you different perks. The more you pay them monthly, the more perks you get, but the perks are your usual colours in names, or having priority in the active list. Nothing else. Not worth the money because there is no love poured into the site from the looks of it.
Honestly a disappointment.
