Hey,
My landlord found out and said he would look at eviction if I continued as (I didn't actually realise this), it states in my tenancy agreement that I can't conduct business from the property.
He found my AW profile and neighbours reported people coming and going so no denying it really...
I now work from hotels and they are fine with that! They're fine with what I do, just not from his property, which is fair imo.
A lot of tenancy agreements will include this clause, and also one that mentions not using the property for "illegal or immoral purposes", which could include escorting (under immoral), so have a read!
