Upstore is a site that is a huge problem to rights holders. They are completely rogue.
In 2012
we removed Paypal and then Avangate processing for them, now they have new processing which we are going to be targeting.
Here are some examples of infringement which remains unchecked.
Upstore are definitely a high priority site for us, removals from the site are rare and files which are removed appear back there within 24 hours.
