Amazon or Alibaba - whatever is dominant in the geopolitical region, is FAR TOO IMPORTANT to not be a clown op.
Think about it. Why would they not grab information about what you search for to buy, what you order to read, or what vector your private ritualistic behaviour is placed in when you are home alone.
That having said, I am pretty sure free porn is also a clown op, to gather hardcore information about your character you would not tell anybody. so be careful what you search for on things like YOUporn or REDtube.
