Can anyone tell me if I should confirm my passphase ?

Got this email from    Lisk Team <business@lisk.io>

Validate your ICO Passphrase!
Important! Every ICO participant should do it!
Hello,

You are receiving this email because you participated in the Lisk ICO. According to our records, you haven't validated your passphrase yet.


Can the owner come out and verify if we should do this?  Is this legit?

I got an email for validating my passphrase.  Is this legit?  Should I validate it or is this send by hackers?

Should I do this?

Also when can we get the bounties for doing the facebook, twitter and newsletter sign up?


Thanks

When is the bounties available?  Will it be after April 11th?

I have done all 4 tasks.  I couldn't get the signature completed though.  Keep giving me an error.


I have invested heavily in this as well and would like to see it go well.

I have sign up for the newsletter,
liked you on facebook
and follow you on twitter.

How do I claim my reward in Lisk from you guys?


Thanks
