That's whats happening a lot on Kleinanzeigen unfortunately. If the price is too good it's a good idea to look on ebay for similar parts or use reverse image search. In most cases that's where they steal the pictures.
The moderation on Kleinanzeigen is slow and relying mostly on users flaging items. It usually gets deleted within a day but everyone who fell for it lost their money if they paid without buyer protection.
It's all hacked accounts so the seller feedback does not matter.
And the scam seller can upload the same fake photos again on the next hacked account...
