See the attached screenshot of my account. I have been playing legit for a long time now, but still got 'slash' marks over some of the pokemon. In the screenshot, you can see only one, but there are many over other high CP mons and 100iv mons and if you transfer them, you don't get any candy. I was thinking about buying a key, but have decided against it.. after putting so much time playing legit and investing money in the account, I dont want the account to be banned!
48 of 50 of my Dragonites are with red line over them. Pokefarmer people are just talking crap how they are undetectable.
From my top 100 pokemons with highest CP survived without red line only 12.. I don't know, if I have to delete marked pokemons.. Btw, when You fight in gym with red line mon, Your enemy is nearly unharmed..
Deleted all the around 70 Pokemon with slash yesterday. Logged in today to find 30% of remaining ones with Slash marks. Wtf! No point using poke farmer or any bot for that matter. Hope some remain to play legit.
