I disagree. We can see all transaction related to an EOS account. If said EOS account is registered to a BP and they update the profile with information we will know it is legit. If the BP choose to update info that is misleading we have a single point to validate and hold them accountable. A BP would be wise to make sure the Profile information is accurate. If they don't they are taking a huge risk.
Also, the only one that can make changes to the profile is the owner of the account and who holds the private key. Also, EOStitan has provided a hash so that if it doesn't match what is on the block chain then we know the profile is corrupt.
lots of checks and balances there if you ask me.
