Yes, they do exist. For example, you received a message from the LOVOO team after you registered. This is one of the official LOVOO accounts.
 
There is also the LOVOO User Research Team. This team gets in touch with LOVOO members to find out more about how LOVOO is used, what wishes, expectations or needs are open and how well new features are received. This helps us to constantly develop LOVOO further and give you and your matches a great time on LOVOO. The random principle determines who is selected for surveys or interviews, for example. Maybe you'll even be there next time. We thank you in advance for your participation, with which you contribute to the further development of LOVOO!

Beware of fake, spam or scam profiles: If you think a profile looks suspicious, you can read here about how to recognize fraudulent accounts and how to report them.
