I use my own phone for punting, but my fb settings are set on the highest privacy settings, and my phone number isn’t linked to my fb. I also never use Whatts app to speak with a WG. Only ever call or text. I don’t have Instagram or Twitter.
I’m a single guy though, so as much as I’d rather people didn’t know what I get up to, I don’t really have a great deal to lose.
I probably should use a punting phone, but I’ve never had any trouble so far.
Even if you do have a lot to lose, I think it would be wise to not let WGs know this. If ever a WG asks, always say you are divorced with no family, and you don’t have a good job. You don’t want to give them a reason to want to target you.
