To avoid sharing a cell with Bubba, avoid:

• Cash Gifting Programs.
  (It's NOT a Gift if You Solicit It,
  Unless You're a Registered Charity,
  and You Report Donations.)
   

• Any Program where You Receive Hundreds or Thousands of Dollars
  when Someone Joins, and Your Recruits Receive Nothing of
  Intrinsic Value They Can Hold in Their Hands.
  (Information is NOT a Product!)
   

• Any Program Paying You Commissions on a
  Monthly Website Fee.
  (Commissions on Tools are Illegal.)
