What groups are you referring to?

This is happening also in FB groups. These fake profiles seem “innocent” but they attempt to engage users, drag them into private conversations, and then involve in (mostly) crypto scam. The pattern is so obvious that in a running group I’m moderating (1M+ members), we're directly banning such profiles whenever we spot them or when a member reports them. I think Strava should too, for the sake of everyone's safety. 

I am also seeing more and more of these each day. Sometimes I open the profile to find the exact same activity posted day after day with photos that are pretty clearly not from the place they are posted (I don’t think Reno, NV has a Little Thailand where they drive on the left). So I report them as “impersonation” and Strava support emails me and says they’ve “taken appropriate actions”. YMMV

I reported one and that seems useless. I think all I can do is to leave all unnecessary groups. Below’s the answer from support:

“

We take reports of violations of our Acceptable Use Policy seriously. We used technology to review your report, and we were unable to determine that it violated our policies.
“
 

If you look at any of the segments they complete, you'll notice a pattern 

Many accounts uploaded the same file on the same day at the same speed and timing, some with ridiculous names (the ghost of Amelia Earhart anyone?). They are all stolen activity data, stolen photos (from elsewhere in the world), and really saccharine titles and descriptions. I think Strava needs to be more proactive and transparent about this pattern of potentially misleading or bot accounts. I cannot be sure what the endgame here is, since I haven't interacted with or read any experiences with them, but I see a sign that something isn't right. 

Even the names on your screen ​@arc88 sound like those “piglet butchering” scam fake profiles in FB groups. Strava really should intervene without relying on user reports… leaving them be is a pretty serious security issue.
