This is a Marina Joyce type thing where one thing is said then its escalates into a shitstorm of bullshit and lies. The pokemon servers are apparently being DDoS'd thats why shits getting messed up or Niantic actually did make some major changes but don't think just because of this that nothing is possible anymore, just like everything that gets patched theres always a new way. if Niantic were so good at protecting the game why wouldn't they do it at the start. Just sit tight and wait for the bots to be updated before coming to any solid conclusions. if u have any questions or anythin to add feel free to post it with links/source/proof otherwise its pointless
TL;DR: As of now all the bots are useless for the important things like farming pokestops and pokemon but you can still do the basics. So basically nothing. Just wait for a new one.
heres what i found so far -
Good news:
Also found out what actually is wrong
Basically Niantic thought it would be funny to change the getMapObjects to f**k around with everyone. And it worked like a m'er f'er.
