Blocking team invites doesn't block fleet invites (trust me.) There's no way to block fleet invites, which is truly aggravating. I tried the fleet thing for a while, it did little to enhance my gameplay, so I left. Now, since none of my characters are in a fleet anymore, I again get those annoying invites all the time. If I wanted to be in a fleet, I'd be in one!

Honestly, I don't even know why people constantly invite people they don't know into their fleets. If I had a fleet, I'd only invite friends. I wouldn't invite anybody and everybody into my fleet. After all, what do you know about some random yahoo you pass in sector space? But, since we can't do anything about the people who do this, please give us the option to block fleet invites.
