Always use completely different profile pictures for dating apps. This is because through Google Image reverse search, a stalker may track your online activity. For example, if you use the same profile picture which is also publicly visible on Twitter, Facebook, LinkedIn and other websites, a stalker can simply take a screenshot of that photo you have put on a dating app and do a Google Image reverse search to track you. Usually, people tend to share more personal information or details about their career on LinkedIn. If you have the same profile photo, a random stranger on Tinder will be able to browse through your LinkedIn profile by just Googling your photo. For stalkers, this would be a significant find.
