@Savannah118 What Helen3 said is true, but I don't think that's what you are doing. I recently had a local cleaner reach out to me in that way, and it didn't bother me at all. It has been really hard to find cleaners in my area, so I was happy about it. Not every host may feel that way, but I appreciated her effort, and we were able to make contact.
AirBnB blocks information because they don't want people to book off-platform, which I completely understand.
There are ways to get around this, by spelling out numbers and or rhyming with certain words. For example, three oh won is my area code. Got it?
You can also provide your full name and location and encourage someone to find you on Spacebook (get it?)
Definitely proceed with caution. As I said, while I appreciated it, some hosts may not.
