yeah that's a 'warn' and your acc is 'blind'. the warn should go away after about a week and the blind should go away after about 10-14 days.
unfortunately, even though the devs claim they update the bot so it isn't detectable whenever they release a new version due to a patch.. it is detectable. As a result there's a good chance of getting a suspension if you bot for even a moderate amount of time.. (i've got 40 something accounts I rotate through so it doesn't bother me as much as it should but it can be inconvenient at times..)
I really wish people would stop using the word 'ban' for everything, a ban is permanent. a suspension or restriction would be a more accurate way to describe what niantic does to botting accounts when it finds them.
