The guy yelling "Look me up on Facebook!" plays into the perception that Apostates try to gather followers after themselves.
The douchebaggery in these tactics is extremely high.
Even as a teenager/early 20's I would have just laughed and shook my head at the stupid idiot apostate and then go back to passing the wine and bread. I used the internet (Yahoo, Excite, then Google) to look for everything and NEVER looked up apostate websites intentionally.
You're free to use whatever tactics you want, no matter how idiotic they are. Just understand, when idiotic tactics like this are used, it does way more harm to the cause than good.
The ends do not justify the means. Subtle tactics work best. Even the elders recognize that a subtle apostate is more dangerous than an overt moron apostate like the ones in this video.
One time I discussed a guy I thought was an apostate with my father who has been an Elder for more than 33 years, PO & COBE for 30 of them. He said, "How do you know?" I told him, "Well, he's probably not. There's nothing I can put my finger on. Just really subtle things." He then gave me the gist of the statement above about subtle apostasy being more dangerous and damaging to the congregation than other forms.
So, in summation, I guess what I'm trying to say is don't be a huge douche and do similar things to what was portrayed in this video. You'll have far more success just asking questions.
