So many of these are dubious. People should be voting against all these challenges imo. The fact that you can find an old house number doesn’t make you right.
Basically you’re relying on information overload to manipulate people into thinking your ‘corrections’ are actually right.
The address of the Auditori De Caixa Sabadell, for example is correct–the official website confirms it.
Suggestion to everyone: vote VALID on these challenges.
No doubt you will now produce 5 replies in an effort to bury this response.
