Yes, it is true! 😮
I tested block/unblock to one of my swap partners.
When an user block to another user, the system display this:
Do you wish to block USERNAME?
If you confirm, USERNAME will not be able to send you personal messages or initiate swaps with you.
and when you confirm, the system display this:
The user USERNAME can not send you personal messages or initiate swaps with you anymore.
In the profile of the user blocked, only is displayed the link “Unblock USERNAME”. Nothing more.
Perhaps a warning message should be displayed when you visit the profile of the user blocked, send a message or open a swap with this user. For example:
You has blocked to USERNAME. This user can not send you personal messages or initiate swaps with you anymore.
