Second Life™ Search Engine - a never ending story

Why is it that I can look for something on the internet and find it? Internet is huge but it's real easy. I just enter words in Google to make my search as narrow as possible and up pops results that are pretty accurate.

Now in Second Life search that is true now and then too. Then over night something changes. Of course there is no way to know what. A changed search algorithm? Or is this a bug?

We run Fort Serenity Waterfalls Store in Second Life, probably the largest waterfall store and we're pretty successful when people can find us. Of course I also think our falls are the most amazing, but I can be biased. That is beside the point.

Since a little more than a week back our waterfalls are deemed unfit to show to Mature residents. You'll find us if you check PG or Adult - or both PG and  Adult (a totally unlikely combo). Of course there is no answer to why search works this way. 

For the ratings were we do show we have competitors marching up the list with the not allowed (?) key word spamming method. They seem to be selling out their store completely - even the store signs are set to show in search as waterfalls.

Maybe keyword spamming is allowed again. Who knows. Linden Lab policies are just getting harder and harder to understand.
