[quoteI only use one phone, fake name for Kik, snapchat etc. I use whatsapp on my phone my real name. Facebook real account set to friends only. It’s never linked from any other account.
Can't an escort just trace your phone number to your real whatsapp accout that way. I dont even do whatsapp with friends and family for that very risk...
A WhatsApp account contains little more than your display name which you set and can be anything you choose such as an initial only (photo and other info is optional), plus it has good privacy control settings.
Girls with your number in their contacts will see you on WA (display name only) and can message you on there which may be an issue if a notification pops up at a bad time but as they already have your number can do this via call or text anyway.
The biggest identifier is your telephone number as many social media apps and accounts link this automatically or hidden within settings, but as you stated you're not on these there's little risk to you. I suggest you Google your number first, also in quotation marks, with and without the space after 'area code' fifth number to check.
For most others a punting phone is the best option.
