Deleted invite links, will never work

Ehhh so this has been a problem for quiet awhile, but if you create an invite link then delete it sometimes later. And tries to use the old deleted one you just deleted, you will get that the link is expired. Thats awesome and works. But bots seems to join throught it just fine, like it never got deleted? 
I can show example if anyone is interessted^^
Thanks alot for taking your time reading this!
