How to spot Sellers with Auto-Feedback?

As said in the topic, is there a way to see in the auction, besides description that it says it's automated :/ are there anyways for us to know that once we give them a feedback, we'll receive it in return instantly?

If you see a seller has a variety of feedback statements in cycle, likely they use software to reply feedbacks.

I am using the software AuctionTamer. A very old one but not well know. It serves auto feedback reply. I see quite a few other companies has such service. Some of them will reply feedback in sequence, some do randomly picking from a pool of statements.

My pool has about twenty statements. One reason is for variety so both buyers and myself won't get bored reading my feedbacks. The other reason is to make the pool a source to insert my keywords on my username and product lines so to please the search engines for a higher number of indexed page on my words : )
