I have a personal message, but it's very generic, I do not say my name on it. Also, I got my dogs excited before I recorded it. You can hear them barking in the background!
I also do not have any real information online - even my email is set up with fake name and information. I hope that will ensure that no one will contact me online unless I have contacted them first and let them know who I am. (So far this has worked well for me)
