User doesnt want to use a escrow from site or Localbitcoins but instead he wants to use btcrow.com
The site itself should be pretty safe and if you are known with the site procedures you will not likely be scammed.
But, NEW USERS, the site works with e-mail confirmations and these e-mails can be easily spoofed.
In that case you will not receive a legit e-mail from the site itself but a spoofed e-mail from the user looking exactly the same but most of the time without a in-site-transaction link.
So, not saying this user is a scammer but he most likely will try to spoof the e-mail to get you to send the bitcoins otherwise he would've accepted any other escrow service right?
