As part of the adult content changes it has been stated that there will be a 'adult' keyword list. Anybody using keywords on this unpublished list will not have their keywords shown to unverified accounts. Unfortunately, this keyword list as compiled by residents testing the upcoming viewer which will implement these changes also has several words that have purely PG uses. Thus creators of content that have PG reasons for using these words will be negatively affected along with the adults.
Unfortunately, this is a massive disservice to all Second Life residents. Those residents who have a PG reason to search for these words will return no results if they are not verified, and if they are then because there is no way to search by context they will get the non-pg uses that they didn't want in the first place. Also, given the history of some words being excluded from search due to a banned word being part of the larger word, and no guarantee that this will be fixed in the final release, this list of words could affect large numbers of content creators and residents who have product that does not belong on the adult continent.
My suggestion on this is twofold.
1. Contextual based search - this needs to be implemented. Keyword exclusion alone will have many false positives for adult content needlessly, negatively impacting mature and pg businesses that rely on the non-adult uses of those keywords.
what that means to me - expand the options for parcel owners. Leave the description field, but add in a keyword field. That keyword field would be treated as meta tags for web pages, the end user does not see this, only the search engine. Once that is in place encourage landowners to populate the description field with an actual description. It allows for better context based off the owner's description of the land and still allows for the keywords that are popular.
additionally - add in a tab for parcel picks like the profiles have picks. This will allow for the search spider to see what other things the parcel owner feels like letting people know about (community shops, or where hair was purchased for the promos, or places to see that naughty furniture in use) and can be helpful in determining edge cases in the software.
2. Until such time as contextual search can be implemented the 'adult words' that have also purely pg uses need to be either allowed in all cases, or will need internal flags for further inspection if the parcel is not on adult land. And then those flags need to be investigated in a timely manner to make sure that the content truly is pg or mature and has a legitimate use.
If something absolutely HAS to be done, I would support making an area of the Mainland strictly for people who don't want any of that content to be viewed.
