Sorry, but at this moment you can not register as a new user.
Link-SPAMmers keep polluting this free service by registering and adding SPAM-links.
Extra security measures seem to help only for a short period of time.
Quite stupid, because nobody will ever see these SPAM-links!
On MyPIP you can only see your own links and, if shared, links of known friends.
True, we never said SPAMmers are smart people ... but they are more than annoying for services like this.
