I made a very similar post earlier today.  Lots of good reasons to know who the creator is and have a way to reach out to them, even if it is through a proxy to maintain their privacy. 

I agree, I think something along these lines is needed. I wrote the below response to the other similar thread and will post it here as well.

I am one of the trail stewards for a local park and sometimes trail sections are closed or rerouted. Sometimes people make new trails by riding down a hillside and then create a segment for it. We go in and remove the trails, but the segment still exists with no way to remove it. This draws unnecessary attention to the old route and can cause extra work for us if people attempt to re-open it. At the very least there should be a feature to archive old segments that are no longer relevant due to trail changes. This could be done either by contacting the creator, or with a voting system (some min number of votes to archive). I would also be in favor of local admins, but at least for mountain biking they should be people involved with the trails somehow.

In the old Strava community the request to be able to contact the segment creator was for a long time the most upvoted suggestion. It would solve soooo many problems with duplicates, incorrect, corrupt or out of date obsolete segments. While Strava is responding to everything else like adding grocery shopping to activities etc they have as far as I know constantly ignored this very valid request. No one knows why.  Should be super simple to implement.

@elliott_holt Nice request, I agree with most points. I think Strava needs a system similar to Trailforks. In my local area there are a lot of old short segments. One of them is a pump track! Actually it's funny when I get a KOM there going 163km/h average. As you pointed out there are a lot of outdated segments that need modifications or removal/going private. There are also segments that do not follow recommended guidelines, so taking competition there doesn't make much sense. I can create my own "right" segments but seeing several mostly identical segments in the results is annoying

Typically the trail builder would name and create a segment, but not all trail builders want to be identified, especially if the trail is an unsanctioned one. 

A very small percentage of segments are created by trail builders.  Only a fraction of those would be ones created by people illegally building trails.  Really, we should not base a decision of whether to do something or not because someone illegally building trails might not want their name seen.  They shouldn't be building the trail in the first place without it being permitted.  If they want to do that and still keep their name out of things, just don't be the one to make the Strava segment.  It's really very simple.

Your opinion, and you’re obviously one of those guys that never build just complain about others work. If all the ‘unsanctioned’ trail segments were taken off Strava you would have hardly any segments. Strava is a **bleep**show, segments are kind of a joke as no GPS times across devices are on a level playing field, making a mockery of KOMs and QOMs. Now if you will excuse me I’m going out to do some trail work and ride, much more acceptable to me than wasting my time on here. 👋

This is more needed than ever, now that you can’t make public a segment that already has a similar one public. If the public one is trash, we’re stuck with it. Its happening right now since the last massive deletion of segments made by strava a few weeks ago.

I’m not sure what the value is in making the segment creator be known.

I’ve probably created hundreds of ride and ebike segments, mostly climbs, often climbs that meet the Strava categorised climb criteria (including putting “cat4 climb” and alike in the segment title so app users can see it’s a categorised climb even though the red circles displaying such don’t happen in the app).

But I have come across the odd silly situation since Strava scaled down the number of public segments of a particular road stretch. For example, Beeches Hill (Bishop’s Waltham, Hampshire, UK) to the hilltop is a cat4 climb, but someone has made an ebike segment that excludes the last bit of the climb that goes past the left turnoff for Ashton Lane… The missing bit is so small that Strava won’t allow a new public segment that goes to the top of the hill, so I can’t create it.

There’s a bit of a knack to creating new segments, but it isn’t rocket science, just needs a bit of common sense regarding start and end positions (especially latter, if it’s not a moderate climb at a junction, you want the segment to end at least a few seconds before the junction).
