on facebook, even if you send one friend request and it get's reported or goes unanswered?

[Dibbie]

No offense, but if I where to see a random friend request from someone iv never seen or met before, even if you where mutual friends with half my friends,5 times out of 10, im not going to accept it, unless one of my buddies told me that they told you to add me, for whatever outlandish reason.

Id suggest sending a message first, and wait for their reply, talk with them a bit, before adding someone.

Start with first introducing yourself, and answering the questions im sure they would otherwise ask or deny your request because of:
Who are you?
Why are you contacting me?
Howd you find me?
What do you want?

Something like maybe: "Hi, im Gorge Cristanza, I found you on my 'friends you may know' list, and thought you where a cool person. Id like to get to know you a bit better, why dont we talk later? bye." answers all 4 questions right there.

If you are doing whats called "Mass sending" where you send alot of requests in a short timespan, Facebook's anti-spam system will think your a bot, and first confront you with the evidence, and if you ignore it, or accept to it, they will then block your account, and send you an e-mail saying you cant access your account any more.

Dont send out random requests in general, honestly, just use Facebook as it is to be intended, and your account wont violate any of the terms of service that no one ever reads.
