As of yesterday, LL implemented their "adult" segregation policy on searches.
The Cool SL Viewer v1.23.4.0 release 10 is already fully compliant with LL's new adult policy. If you are using any older version or release of the Windlight branch (v1.2x) of the Cool SL Viewer, please upgrade (
Get it here).
The Cool SL Viewer v1.19.0.5 (legacy renderer branch), although still allowing to access adult sims when your avatar is considered as "adult verified" (a simple "payment info on file" flag in your profile is enough to be considered as adult verified), does not any more return adult search results (since it is not fully adult compliant and the servers now refuse to send such results to non-compliant viewers).
I will backport the adult code and will implement it into the next releases of the Cool SL Viewer v1.19.0.5.
