there is also
The following problem(s) were detected:
The requested member was not found or is no longer valid for viewing
I just can't find the last one
This is one of three different messages AW shows for profiles that no longer exisit - I've never understood the difference in them all though.
The 404 means that the profile has been completely deleted, so the SP has deactivated the profile and the requisite time has elapsed for AW to remove the page.
The "not found or no longer available for viewing" would be if the SP has set the profile to "Seeking Services" rather than "Providing Services", which is what I believe they do if they wish to go off the radar for a while but not lose the profile completely.
The third case I can think of is when you get the message along the lines of "The
name of SP is no longer available, here are others you may like" and gives a search result for the area in which the SP was registered. I guess this might occur at the "halfway house" of the first case, where the SP has deactivated the profile, but it has not yet been removed. It must still exist in the system for AW to know the name and location.
