Bastards in Auction House

So, I do use AddOn "Auctioneer" and I see a lot items, that cost >999%. For example stack of Linen Cloth that costs 50k gold... Because of these people's auctions, my Auctioneer database is inaccurate... Is there a way to avoid auctions like these (when scanning) or is the any way to bypass it? :/ Thanks and have a nice day/evening.
p.s. Moderators, I'm sorry if there is a post like mine (I didn't find it), and I'm sorry if it's not the place to write such things. I'm not a frequent guest in forums.

My advice to you is learn all the prices yourself. Do not count on Auctioneer to give you your prices. That addon wasn't accurate on retail so you would be foolish to completely rely on it.

And there is no way to avoid such auctions afaik.
