Is there are anyone still playing this game?

In my experience the Guild chats can be as or even more active as the official IOU chats.
If you're a very social player you should look for socially active Guilds to interact with players.

I'd recommend checking the #guild-and-party channel in the official game Discord chat to find the guilds I'm referring to.
Here's a link to the Discord - https://discord.gg/WfcvtZm

Hope this helps
