Your 2nd link is the crazy place.
Most of that site has problems similar to those in their LTUP section.
The secret and anonymous moderation and reporting system is the biggest down fall of the site in your link.
Moderation is by the owners teenage daughter and the problems are what you would expect when children are in charge of Adult conversation.
The paying members seem to have access to enough of the site for hacking and tracking other members.
Some members call the FBI and other agencies on the other members
( I know of 3-4 times so more would be expected)
Their rules and moderation are set up for a few select to play games.
The owner likes it that way as the Soap Opera effect keeps traffic high for sponsor $$$$
That place is not safe for children at the least and smart adults would stay away.
LTUP is their worst but it is scattered all across the various forums there, 50-75% of them at a guess.
With reasonable rules and some real moderation( as opposed to vindictive moderation) there is no reason why adults cannot discuss our future in a reasonable manner.
Another possible help would be if the sub(?) forum if on U.S.A. politics that only eligible/registered voters would be allowed to post?
