There are a few bots "answering" questions. Look out for obscure disjointed phrases which only loosely relate to key words in the question.
You can also check the profile. If it's generating answers 24/7 it's not sleeping like a normal human !
High % best answers are also suspicious, it indicates multiple accounts.

No. The questions and the answers are or were human generated. They were generated a few years ago and now they are being recycled with new accounts to build up points. When they have lots of points these accounts will be used for a spamming campaign.
