My source was the following from steemitblog:

Which said the following:

>The current system also incentivizes attackers creating multiple accounts in order to acquire free STEEM, which again increases the overall cost of maintaining the protocol. To solve this problem, we propose a new method of burning STEEM (i.e. destroying the tokens and removing them from the token supply) on each account creation and crediting the account with permanent minimum bandwidth instead of providing Steem Power to the new account.

As always, the steemit team is so focused on the abusers they haven't thought through why the abuses are happening in the first place. It's because it's pretty much impossible for a noob to go from 0.1 SP to 50 SP legitimately. They either give up, or figure how to game the system by opening multiple accounts. The option of writing and getting discovered is blocked to them because it's now too difficult to even earn $0.02 which will give them around 0.017 SP. They'd have to toil for aeons with thousands of $0.00 posts and a few $0.02 posts before they even break into three figures of steempower.
