Hello @ulfhjensen
Thanks for posting about this.
There are a few reasons a suggestion could appear in your feed: a mutual friend on Strava, from your phone's address book, from the address book of another athlete, or through Facebook.
If you've given Strava permission to access this data, either to your phone's address book or signing in/connecting Strava to Facebook, then you will see suggestions from those sources.
If you did not give us access to your contacts, the person who was suggested to you did. In other words, if your email address happened to be in their contacts, we will suggest them to you as someone you may know.
You can stop syncing any new contacts from your phone by removing permissions to your phone's contact book and/ or Facebook. You can also remove any contacts we've stored by going to the app's Settings> Contacts > toggle off Access to contacts.
For more information please read our article on how we use contacts and connections.
