I just signed up and got the notice that if we do not post within 30 days our membership is subjet to weed routine. That would be fine if it were a free service and your income was truly derived from willful donation but since it is forced that policy of weeding out members needs to be reviewed.
You also should give new members 30 days to use the site before forcing the fee. How do I know it will be beneficial to me if I cannot read anything? I am willing to pay the fee if I am confident that the site is worthy but until I can read it that is not going to happen.
If you post NOTHING AT ALL within 30 days then it's assumed you're not coming back.
Take a look at the Joomla community forum. It lists more than 310 000 user names with zero posts and another 70 000 with one post and another 42 000 with two posts ... nearly all spam. WebmasterWorld does not operate like that.

The vast majority of this site can be read by anyone without paying any fees. There's only a small number of private topics for paid membership listed at the top of the page.
