It seems this has come up in a few whatsapp groups, but I thought I'd start a forum thread just to see how big of an issue this is and whether anyone has found a solution.
A few of us have had QOMs stolen by Strava spam accounts. I don't care about the QOM, but the spam account (which mentions links to porn websites in it's profile, so I think it's a weird way of advertising those?) posts rides that followed mine very closely, and circled around my flat. I've got the privacy settings on, so that should help, but it feels a bit creepy. The 'ride' the profile posted was from 2017 (though uploaded to Strava last night) so at least there's no one actively following me around.
People are targeted from different profiles, which disappear again quickly, but the link might be that we're all connected to Dulwich on Strava.
I've reported it + profile to Strava so hopefully they'll find a solution. And I've got no QOMs left now so that should solve the issue for me as well now .
I've seen a few of them this week as well, but the routes are round where I used to live. The profiles have all disappeared before I've had time to flag the ride so I'm hoping it's something Strava is on top of.
