I've done a pretty deep dive on this over the past year so I can offer some thoughts.
The main thing to watch out for is whether the platform actually verifies its users in any meaningful way. A lot of sites claim to but the reality is very different once you're inside.
A few things that have helped me:
- Use a secondary email address you don't mind getting spammed
- Never use your main payment card — virtual cards are a lifesaver
- Take screenshots of billing agreements before you click anything
- Check the cancellation process before you subscribe
Currently using Turndate as my main go-to and it's been solid for the last few months. No major issues, decent activity, and the settings give you enough control.
Take what's useful and leave the rest. Everyone's situation is a little different.
