I don't trust them either as it is . I mean I bought from top rated ebay sellers with 5-10 years old seller accounts. They might not want to put their business at risk with negative feedback. I would be happy if these accounts can be used for 1-2 years and all my files are stored in separate onedrive and another gdrive as well, so I won't loose all at once.

. I don't use these for backup my files in machine at the moment, just using to store files that are downloaded to my seedbox and I have direct access for all cloud storages from seedbox.
I don't have any dealing with ebay sellers either and didn't share any store links . Just shared my experiece.
