I find it all depends on your approach. Most won't answer if you are using a text app. Or if you are looking for short notice appointments. Or if you're not using full sentences. Try a good introduction, like this: Hi, ____ , how are you doing today? My name is YOUR REAL NAME and I saw your ad on Lyla today. I'm wondering if we can meet for 90 minutes on Feb 27 in Halifax at 4:00pm for an incall appointment? I can send ID and a deposit if necessary. Hope to see you soon, thanks.
Not saying it's foolproof, but it's been working for me.
