Why is all my negative feedback removed by EBAY?

[aimandclick]

Last 4 negative feedbacks I left were all removed within less than 10 minutes.

ALL of them were fully deserved by those sellers and I was very careful to follow ALL RULES about feedback so there would be no good reason for eBay to remove it.

In all cases they CLAIMED that the seller:

1. Called them

2. Appealed the feedback

3. Got approval for the feedback removal.

Since that is IMPOSSIBLE to happen within 10 minutes, let alone because there was NO REASON to remove the feedback, the above statements by eBay are LIES.]

Please explain.
