What is barrucada that you are mindful of him???

Doesn't sound too pleasant to have all your links go though their censoring and monitoring.
And it might make them culpable too when the competition want to get twitter in trouble they can use it as an attack vector in court, like say "you linked a brit to a site about suicide and that makes you responsible" and BS like that.

On the other hand, obscured links on twitter always seemed madness to me, I know from chats what links can lead to, and you have to be quite strong (in nerves and stomach) and clever (to avoid attacks and malware) to handle that.
