Got an invitation email today as well (mine is #30549 if you care to compare). Scam flags:

• The site currently says that "32.29% tokens remaining", which more or less the same number as what one could see 11 days ago.
• The srsk.co domain has an invalid certificate (not something you should spare upon when begging for a million dollars).
• The chatbot seems to only implement the "start", "account" and "send" commands. Everything else is fake.
• The block explorer is fake or broken:
  • Unable to browse blocks before 2079. Blockchain without a genesis block? No, thank you.
  • Give him any account address and it will tell you all the same stats about it.
• No Github or any indication of actual development.
• The @statusm user, who claims to be "a member of the team" is an account registered some days ago for the sole purpose of posting these two comments here.
• In general, the attempt to "hide the team" (not even finding a single person willing to come out as a legitimate representative) aligns much better with the desire to get the money and run without leaving a trace than anything else - the excuses "we want to be exclusive" they post on the site look lame to me.

For the reference: the email I received came from Aiden Hamil (aiden@srskteam.org), the srskteam.org domain was registered just a week ago and is bound to a generic mailboxhost.com email provider. Google does not know of any notable developers with this name.
