It all depends on the community and how people get along there. Spoofers and multi-accounting is in many places not that frowned upon because they play by the rules of the local community. That’s also the case where I live. Do I approve of spoofing? nah. Had I in over a year any trouble with local spoofers? Nope. Only on a few occasions, we got those from elsewhere, since a 100% larvitar once spawned here and within minutes the whole town was occupied and everyone got kicked out of their gyms and sid gyms were aggressively defended till the next day. Happened to a lesser extent also on two other occasions. I can see how this is a huge problem in places that are costantly targeted by spoofers though.
Spoofers who decide to take over gyms in order to get golden medals are beyond annoying. You can kick them out, but in a couple of minutes they will be back, since unlike you, they can just fake their location next to the gym and be back within minutes, unlike you who has to travel to be in range.
Multi accounting depends on where it’s used and how people use it. In rural places where there is a lack of gyms and players extra accounts more or less keep the community alive, due to the lack of people who can take down a raid boss. Also in such places people who have two accounts have them on different teams, since it can take weeks before somebody comes by and knocks your pokemon out of the gym.
In cities where you have constantly enough people for raids, it’s a different story, since you don’t have a lack of players and it’s unlikely that your pokemon will stay in the gym for days or weeks.
Also while I can see how another backup account comes handy, I fail to see how having 3+ phones can be a fun experience. That looks more like a chore and kind of defeats the purpose of the game…
All in all, from my personal experience multi-accounting, was less of an issue, then again I live in a small town and without multi accounts we could forget doing half of the raids, since there are not that many people and not everyone has high level counters.
That being said, it also doesn’t help that Niantic’s detection of cheating is absolute garbage. I know people who are spoofing for years now and never got a warning, even though their constant location changes should show that something is not right. Ok… how many people can travel daily from Japan to Europe and then to the USA? Not to mention their game locks in locations of catches, but not of raid passes, so those who spoof can raid and then if what they get is not good enough for them, they can flee and go to the next raid regardless of the distance. A simple change to the system could eliminate this and we would no longer see things like people live streaming raids from their room. I won’t drop any names, but a quick youtube search shows which people I mean.
On the other hand, some people, including me, have gotten false positive warnings or even had their accounts deleted(not just in PoGO, but also Ingress and harry potter) and Niantic’s help and customer service is by far the worst thing ever that a person has to deal with. You only get automated messages, get no explanation and I highly doubt anyone even looks into your case. I’m sure that only a fraction of warnings is like this, but each false flag is one too much. In case something like this happens to anyone, the best thing is to either do a factory reset on your phone or start playing on another device, since who knows what the game considers as third party software at this point. You can ask their support for feedback but you will be formally told off and won’t be given any explanation since even they can not provide any details.
After going through this I frankly stopped caring about who cheats. If people who do not cheat can also get hit and Niantic doesn’t acknowledge that, then this is even worse than them allowing blatant cheating. Their support also deserves to get nuked off the earth, because I have never come across at something so half-assed. I already dealt with strikes on youtube, including things like misidentified media, wrong copyright strikes and even impersonation, all of which I could clear eventually. Here, however, you get nothing. Just the standard copy-paste message of "Violation of ToS results in … ", with no details provided and I’m certain that no one even bothers looking into what caused this to begin with. One can only hope that whatever got falsely identified by the system as third party doesn’t happen again, since then you are screwed, due to the ban appeal being a joke and a waste of time, because it’s like you are arguing with a bot, that can say only 5 different things which are all just the same message just differently worded. It’s quite similar to how they reacted to the weather change malfunction with slakoth CD. Everything is your fault, not theirs.
I went a little off-topic here, but this due to my personal experiences. I will probably make a thread about this in the future since this doesn’t get mentioned too often and is normally ignored due to happening only to a fraction of people. However, after experiencing this first hand, it is something that Niantic should get called out on. Their employees are obviously reading what people post online and certain things like missing shinies and some game exploits via new features have always been fixed within hours after people started talking about them.
