About the invitation
The invitation itself is for everyone to introduce high-quality users to join our big family.
On the one hand, we don’t want users to spam invitations. On the other hand, we also want to give newcomers a chance.
For PT, every contributor is worthy of respect.

However, there has been news recently that some people have sent invitations to hope that the magic power will be returned after a period of time.
I am here to make it clear that this requirement is a transaction.
Please don't do this again.
