I just had a match with a woman i allready know, and i also got her phonenumber from earlier, what i just recognized...

So, what happend? I had a nice convo with her about our dreams and i felt like sharing my x.com profile with her, where my project diary is. So i sent this x.com/PUTYOURPROFILEHERE link and bam! I had to reverify on tinder. Uhmm ok, so did it... now neither i get her messages nor i can send messages to her. Tinder just blocks our convo. I remembered that i had her phone number from the earlier match, searched for it, found it and called her. Indeed, none of her messages to me nor mine to her where delieverd!

I think this happens more often that you can think of.
If you are suspicious if you are shadow banned, this might help:
1) Looking at the profile of your matches just show photos and normal details, profile text and distance is hidden
2) if you send a message in the app, open the website in a browser, the just sent message does not appear
3) hard to check, but you do not get likes nor messages

I think tinder should be sued fotr mental cruelty!
