scenario: you know a chud at your workplace. he shows you a 'funny' meme on his phone and you peep his twitter handle. it's LoliHitler88. you hate this guy so much. can you put his real name and face on a billboard next to his greatest twitter hits if you don't call him any names on it. is that considered harassment or free promotion. this is a hypothetical
the fbi can trace it... your shitdick IT firm or craft supply store or warehouse or whereever you work can't
Then I guess the next question would be would there be a reason for authorities to get involved? Is this a case of harassment? Anyway, it seems the best recourse is to print it in black and white anyway to avoid any tracking dots.
