Sir Saphiel:
It's because your age is listed as 99 years old and the maximum age parameter in the profile search is 75. So it's trying to look for a profile called 'biggerthebetter' between the ages of 18-75 which doesn't exist because the only profile called 'biggerthebetter' has an age of 99.
(similarly, height parameters are 5'0"-6'7" and weight parameters are 100lbs-600lbs, but you don't fall outside of those ones)
Thank you for this explanation. It answers a question i’d not yet asked about someone else’s profile, and for the same reason as biggerthebetter’s.
It’s actually kind of a nifty trick for anyone who might not want their profile to be searchable, though of course the profile still displays when they post content and someone taps their avatar/name.
