I don't get it.
You can easily evolve gyrados in a couple of months if you just made magicarp your buddy and walked 2-3 kms everyday.
I evolved a gyrados the same way. Legit way.
I understand that tyranator would be harder but I'm a legit player and I evolved it as well by making it my buddy and feeding it rare candy.
I evolved both of these without spoofing and just doing solo raids.
It's hard but it can be done in a few months.
I cherish both of these Pokemon's because I know how hard it was to evolve them.
If I had spoofed, I would have not had that same feeling about them.
I'm not trying to be all saintly but i did try spoofing on an alternate account but soon lost interest because I didn't enjoy it as much as I knew that I was not getting all those pokemons legit.
To each his own. It's just a game but IMO playing legit keeps the game interesting and when you finally get that elusive Pokemon, it's worth it.
