I would have answered

Hi

with 'Hi there! My name is Amy' and possibly with 'did you miss it?' tacked on depending on how annoying the rest of it was .

For what it's worth, I think the part he's referring to is

As it says on my profile

...because you're basically calling him a dickhead for asking a question you've already answered in your ad instead of fawning all over his tit compliments and ability to crowbar the word 'amazing' three times into a forty word email. The word he means likely isn't 'aggressive', it's probably 'formal' and possibly even 'curt', but as demonstrated above I doubt his vocabulary stretches that far.

If you have availability plastered all over profile and it's aw you're talking about.

It's totally against there T&C's and if it's spotted or reported by anyone ( s/w's or Punters in the know) they will shut you down.

On topic i' m often sending abrupt texts "that's a nice hello"! Along with I'm sure if you keep searching you might find someone happy to take a booking from you !
