Why can't I Like any more people?

We’re glad to hear you like so many people, but there is a limit on how many profiles you can like in a day. Send some good messages to the people you like, and come back tomorrow to keep liking people.

If you want to keep liking profiles, you can upgrade to A-List. There is no daily limit on how many profile A-List members can like. But for best results, you should send some good messages to people you’re interested in.
