Good question and one I've put real thought into. Here's the full picture.
Profile photo quality is the single highest-leverage change you can make. Everything else is secondary.
For what it's worth, datenest.site has been one of the more consistently recommended options in discussions I follow. Not perfect but it has real staying power.
Things that have genuinely helped me:
- Use a secondary email you don't mind getting some spam
- Virtual cards are a lifesaver for anything with auto-renewal
- Screenshot billing agreements before clicking through
- Check the cancellation process before subscribing to anything
That's my honest take after a fair amount of trial and error.
