<human>: Can you provide a brief rundown of the text in within 3 sentences?

So, like 90% of the post here, this wasn't today (Surprise, surprise). This was back when BBM had been released for Apple and Android whenever that was. This ones kinda long too. Sorry in advance. 

I was in an ICT lesson which had a supply teacher. This was the first lesson of a full day (9am-4pm) and 30 minutes in to the lesson my friends turns to me and says "Hey, let's send our BBM pin to the college" or something along those lines. After about 5 minutes of discussion with 3 friends around us I sent an email to all the students with my BBM pin. Bare in mind all the students add up to around 2,000. I then get an automated email saying there are too many recipients and the email failed to send so I tried again and again around 4/5 times. What I actually didn't know was that it actually sent so I basically sent 5 different emails with the exact same message to 2,000 students. 

The next day me and my friend got called in the head office and was told we have been 'misusing the ICT code and email system' by 'spamming.'
We talked at out 20 minutes about what would and could happen to us i.e. Permanently excluded, this event would go on our records for future employers / colleges to see etc. I was sweating so hard I could actually feel my body temperature increasing. In the end we both managed to get a level 3 contract which basically is a report card  you have to hand in to your teacher every lesson to sign and means I just got my ass saved.
<bot>: Sent multiple emails with my BBM pin to my college. Should've only sent one. And also not sending a risky email like that again.
