Speaking of legitimate blocks!
I have set up a Telegram channel informing about new blocks found on kano.is. If you use a Telegram Messenger, you can click this link: https://t.me/kano_pool and subscribe. New block notification should arrive pretty fast (after the pool finds a block, of course!).

So far only new block notifications are set up, and I don't think we need other messages there. Certainly, there's not going to be any spam or other kinds of unwanted messages there (that's why it's a channel, and not a chat!).

Feel free to join!

Feedback and ideas are very welcome!
