You are not new to bitcoin when
- You say new to "btc"
- You say "will do in smaller increments"
- Familiar with Skrill, PayPal and Western Union
I see nothing wrong with the way he phrased it. "New to bitcoin" does not have to literally mean "hey, I just stumbled onto this forum and I'd like to buy one bitcoin, even though I've never heard about it!". If he's willing to buy a bitcoin, then I'm sure that he did a little research on it and read a few pages of trades to figure out how things worked (it'd be idiotic not to, before spending $1200 on something), and calling him out simply because he says btc or "small increments" does not mean anything. Being familiar with other payment options is irrelevant here.
When you introduce yourself in a deceiving way, you are more than likely to deceive people.
There is a difference between alerting the community about probable scammers and being a general dick to newbies because you see other people do.
