@rorrr: You've been hellbanned for almost a month.

His comment:

> It's nearly identical.

> There are around 170,000 english words (including all the obscure ones you've never heard and have no idea how to spell).

> Number of 4-word combinations:

    170,000^4 = 8.35 * 10^20

> Lowercase (26) + uppercase (26) + digits (10) + special characters (36) = 98 characters

   98^10 = 8.17 * 10^19

> An order of magnitude difference.

> And if they start bruteforcing with the simpler words (which you used in the example), there are only 5,000 - 10,000 of them, the number of your combinations drops dramatically:

    5,000^4 = 6.25 * 10^14

    10,000^4 = 10^16

> So unless you use very obscure words in your password, you are doing much worse than you think.

For good reason; please check someone's comment history before advising them of this.

Well 2^48 ~= 2.8 x 10^14, so it's not as bad as you think for the simple words version (which is the same as 8 characters chosen from 64 choices)
