As of January 13th, 2012:
CrazyTown shut down. The site used to be one of the main Sims 2 sites hosting a lot of content ranging from mods to lots as well discussions on generally anything. When Sims 3 came out, CrazyTown welcomed new members into its fold by hosting new Sims 3 content. The owner made her decision to retire fully from the Sims 2 community and move on to other things in her life.A special shoutout to The ISZ and Sleepycat for hosting CrazyTown for many years up until this month! Thank you both for bringing the community together to enjoy Sims 2 and then Sims 3.
BUT, a new site opened! It is very very identical to CrazyTown! In fact, many of the members from CT moved to the new home and settled there with their own sections. You must register in order to view the boards at the new site.
New Sites:Twallan's NRAAS Wiki
Twallan, one of the well known creators of Sims 3 content, decided to set up his own wiki to host his own mods after The ISZ announced her decision in December 2011 to close CrazyTown. His site shared the same server with CT.
I do not believe you need to register in order to download his mods, but I do believe you need to register in order to post comments there and/or follow his wiki as your personal feed.
The mods there are for Sims 3 only.Simbology - Mods For The Sims 2
While the site retained its original title and look, a new staff has taken over to keep the site open for the Sims 2 community. D_A, Boiling Oil, Zephyrzodiac, Zirconia Wolf and Miros1 stepped in for Twojeffs to keep the site open so people may discover the good Sims 2 content TJ made and hosted. ACR and Inteen are still hosted on the site, BUT ACR is now unsupported with no further updates. Inteen is now hosted "as is" with no further updates.
However, the staff will assist with questions pertaining to any of TJ's mods including ACR and Jase's Inteen. Ask these questions THERE. Not here.
TJ made his official announcement in December, 2011 that he retired from the Sims 2 community with no further intention to update or create any more new mods for Sims 2.A special shoutout to Twojeffs for hosting his mods for Sims 2. Thank you, TJ, for ACR! My Sims haven't been the same since then! Thank you, Madcat256 and Jase, for keeping Inteen updated to Apartment Life! My teen Sims haven't been the same since then!
There is very little Sims 3 content on the site.TFM's Naughty Sims Asylum
This is an 18+ site with both general and mature content. You must be 18+ to view the mature boards and agree to the rules before you can post. This does not mean you can swear all you want, be rude to everyone, post adult content that demean humans in ways that may violate the site rules (just like ISA) or be spammers/bots there. The site hosts both Sims 2 and Sims 3 content with a few off-topic boards.

Sims 2 Adult Sites:B.A.S (Back Alley Sims) - Adult Rated Site
You must be 18+ in order to join the adult-only site for Sims 2 and Sims 3. Chris Hatcher has made major changes to Sims 2 with a couple of mini packs allowing Sims to have hospitals to go to for childbirth, sickness and whatnot AND allowing Sims to have religious beliefs. Several adult mods are available there with constant updates as well discussions pertaining to Sims 2. There is Sims 3 content as well. The staff also has a family-friendly site for both Sims 2 and Sims 3.
Will update with new links to either Sims 2 or Sims 3 sites when I come across more out there.
