The difference between when the average user reports your photo & when Lululemon reports your photo is that Lululemon participates in the VERO along with many other companies listed here: Vero Participant Companies “About Me” pages. The average user can report your image to eBay for copyright infringement, but when someone registered with VERO does it, they also have the right to request your personal information.
eBay’s VERO policy can be found here.
I also would like to mention that at one point, Lululemon had Facebook shut down one of the most popular selling pages on Facebook. It also froze the accounts of the administrators on that page. The stated reason was copyright infringement. So, the admins had all of the Stock photos removed from the page & coordinated an effort to remove all stock photos from all pages. To this day, no stock photos are permitted on any Facebook selling page. Personally, I think it has helped deter scam artists who sell things they don’t own. (If you have to take your own pictures, how do you post an ad without the item? I suppose it’s possible, but it becomes more difficult.)
I know I haven’t covered the entire breadth of this. I find this subject too dry to elaborate on. However, I thought it was important enough to cover. Some people are new to eBay or new to selling Lululemon and may not be aware of Vero policies. I hope that my small effort to prevent your ad from being reported, removed and your privacy being compromised by Lululemon & eBay will be heeded and I can help everyone have a positive eBay experience.
