Used stuff and I don’t mix anyway.

With a practical purpose and curiosity, I contacted this person through a well-known online community. After a couple of emails, which were exchanged within a day, he yelled at me.

S C A M M E R!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Look at the word, typed all in capital letters. Look at the spacing, and the amazing string of exclamation marks (There are 74).

He also kindly told me that he was older than 2 days. I am afraid the original sentence is unsuitable here so I am not going to copy and paste it.
In terms of linguistic politeness, it was a very interesting experience. Obviously not pleasant, though.

So the takeaway is this: I should stay away from those guys.
