Nothing is private nowadays, how do you women communicate? Through mind reading or do you fly birds with notes? it's just a number and info being saved, 99% of time with a hobby burn number.
Some providers need to not use personal rw info, don't use your primary number or e-mail for starters to get with clients, you wouldn't believe how many rw names pop up from a e-mail account or number. This goes for YouTube and social media accounts also.
