The service was created in 2011 in the Czech Republic. It is an online forum where the users can share their experience with phone numbers, both annoying (mostly telemarketing, surveys) and useful (e.g. couriers, offices)..
Since the beginning, the service has been received very well, which led to localization into more languages. Nowadays, the forum exists in more than 20 languages and 34 countries throughout the world.
The service is intended for anyone who wants to identify the owner of an unknown phone number. The creators of the forum have also recently created the mobile app Call Insider for Android phones. This app, which is connected to the database of the website reverse-lookup.co.uk, also allows users to automatically block telemarketing numbers.
Came up on my phone that they called from Leeds three times in a week.
Claims to be a company called RED STAR using your full name.
Said they would be getting a refund on a loan I am supposed to have had. Not had any loan for 26 years. Didn't give them any of my details so don't know if just a nuisance or unsafe. But they must be trying to make money somehow.
I have now blocked it.
