What is how to know if someone blocked you on tinder?

If someone has blocked you on Tinder, there are a few ways to know:

1. You can't find their profile: If you used to be able to see their profile, but now you can't find them when you're swiping through potential matches, it's possible they've blocked you.

2. No messages: If you used to message them, but now your messages aren't going through, it's possible they've blocked you.

3. No match notification: If you swiped right on them, but didn't receive a notification saying you matched, it could mean they've blocked you.

4. You can't see their activity: If you used to see when they were last active on Tinder, but now you can't, it's possible they've blocked you.

In general, if you can't seem to find them on Tinder and your interaction with them has abruptly stopped, it's likely they've blocked you. However, keep in mind that there could be other reasons why you can't find them on the app.
