Do all people who try to be "friends" with me on LinkedIn (and that I have never met) realize I will ping them for sponsorship for @ph0wn CTF? It only seems fair ;P
[My advice if you want to connect with me on LinkedIn: at least include a message saying why, or where we met, otherwise, I'll just turn it down]
And reminding my followers that we're looking for sponsors. Best way (in my opinion) to train your teams, reach out to talented people. Worth 100 CVs ;P
