Free Cloud Mining.... is at all a scam?

Writing on my phone so won't have a ton of "tools" to perk up the post, but wanted to ask this.

Auroramines.com is offering 100h/s free to all users.... it doesn't seem profitable, and likely a scam. I think?

Curious to hear others opinions on these sites. Is it legit, or the old if it seems to good to be true story?
