No wonder there are so many trees on Ancestry with rubbish on them! Like, for example someone born and bred and died and lived whole life in England, has a record attached and death listed as died in "Indiana, USA" etc

I don't think they even check the certificate properly to see if it is the right person. Many trees with my family are like this, and they have added half siblings/steps etc. I know at the end of the day, my trees are right, and theirs looks like a maze with many twists and turns.

EDITED: I got a hint the other day, that they had found someones parents!! Guess what, I already knew who they were!
My emphasis.
Ancestry do not check hints - they can't possibly. I just checked and my main tree currently has 64 959 active hints. Ancestry has somewhere over 100 million trees. Granted my tree is very substantial, nevertheless at a conservative estimate, I would suggest the comparison checking generates at least a million hints a day (I think it's probably actually several million, but let's go with just one million.) Even if they were simply to perform a 1 minute check on each hint, and assuming a working day of 7 hours, that's 40 people.
What the hint system does is it constantly checks and updates all the documents soucres, names, dates etc on those 100 million plus trees and when it finds what looks like the same information on two different trees it sends a "hint" of a possible connection. It is up to the USER to check if the hint makes sense. Sadly as we all know, not everyone does, and even careful researchers still make mistakes.
Edited to Add: I realise I may have misunderstood the post to which I replied. I thought at the time it meant they thought Ancestry didn't even check, and were criticising that, whereas reading it again I suspect they meant the person adding a birth death marriage etc based upon a hint.
I think the problem there is that many people THINK that Ancestry does check everything for them, and therefore that the "hint" is established fact, not a possible avenue for research.
