I don't see a post#20 in that thread.
There isn't one now. The member was banned so all his posts were deleted. They no longer appear in that thread (including #20) so of course the number of posts has gone down.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
