I've been on mingle for less than a week (the paid version), but find it almost unusable. Every screen is flooded with spammers from all over the world, and it would be a full time job to maintain the screens and delete or block them, IF mingle even allowed it. It also states seems like they conciously avoid letting you control your environment. Delete likes - nope. Delete views - yes, but they come back. Sort by distance - nowhere. Limit tolocals or even same country - not that I have seen.

Any tips on how to limit things to people I might actually be able to mingle with? Help.

I AM a pie member, and the inability to mark read or delete who likes me it a major flaw. I joined last night and already have my multiple screens of overseas scammers. I will never be able to find a local without a lot of work. Please consider adding some combination of:
Mark as read
Hide from likes me
Sort by distance after initial read/view (new at top, then sort by distance)
Filter to distance limit
