Blaming the CM for alleged cheating is like blaming the meteorologist for your rained out picnic.
A little bit of comedy here. There were times I would love to throw a shoe at the meteorologist for giving us misinformation about the weather. This was in the 1980s when I was a kid that was going to enjoy a day at the beach. Instead the rain came about. It was from then I decided (through decades when the internet was commonplace) to go into sites that are trusted for my weather information.
Will cheating result in a mass exodus of "honest fairplaying" player? I think not.
Now, seriousness sets in. If you weren't in a game that had a lot of players quit over cheating tactics then more power to you. However, I was part of two games through my gaming life that I can say had a mass exodus of players due to cheating. In that time, it had affected the gaming economy of certain servers (in the case of gold botting cheats) where normal items were overpriced, making it hard for those to normally buy from other players because of inflated greed. The other, I had previously mentioned, was cheats duplicating items and equipment (especially from the "premium currency" stores); in the same manner that diamond hacking I read about from other forums is on this game. Or, as they say, why buy when you can "hack" your way through? Some of us have standards and would not resort to such.
So basically, cheating does affect everyone. Lack of support from support (in dealing with cheats) is what drove the final nail on the game's coffin. Will this happen on here? I don't know. I can't say "yes", but I can't say "no", either. At that moment, it'll be on the support's hands in dealing with such through their avenues.
I don't know how the regulations are in your country, but in France you can't punish without proof and any proof must be beyond doubt.
In the USA, it's pretty much the person gets arrested for the crime being accused of. Charges brought and time spent trying to see if a person is innocent or guilty of said charges. While I get a person can be guilty for the crime committed, but what of the innocent one that had to waste days, weeks, months, or even years until he/she was proven innocent and cleared. Will they give him/her their time lost back?
When you go after a person, (as you have stated) you must have proof. But what if said proof was given and nothing was done? Justice is too lax these days. Reminded me of a time where I called the police because of a trespasser on the property and they have the gall to ask me if I was sure that the person was trespassing; sure, I guess I can go outside and ask the person if they were trespassing along with if they were armed, going to rob me, going to kill me if I don't kill them first among other things to respond back to the dispatcher taking the call, or they can do their job and send someone out to investigate.
Just to throw in something else: What is described here can be compared with "absolute justice" (more information here:
https://onepiece.fandom.com/wiki/Justice#Absolute_Justice). "Supporters of Absolute Justice believe that the eradication of all evil and illegal activities and the prosecution of those who violate the government's laws is the highest priority, even if it requires sacrificing innocent lives or engaging in immoral acts, since the end justifies the means." I am not a fan of that type at all. Many here in the forum already know how I act, that I care for players and try everything I can do to make the game a better place for everyone.
This whole topic about the specific guild here on beta get's annoying, if you receive multiple reports every day from the same players, you check them almost daily and react depending on your findings. However, I know that the part, where I check it is a black box for you, but I can't give you any more details, since every bit will help cheaters getting harder to find. For example (will not say if this is true or not): I say we track every click in gbg and ban, if you make multiple clicks on the same position or if you do more than 2 fights per seconds.
Now, cheaters will set their scripts to slightly vary the coordinates and cap their fights at 2 fights per second. They still cheat and don't have to move the mouse or do clicks and will get undetected. And since we confirmed, where and what we track, way more will abuse it, since they know, they will not be detected.
Sounds bad, doesn't it? This is exactly, what we want to prevent.
In this day and age, it's pretty much "you or the other person".
As to the cheating bits, they will always find some kind of way to circumvent. In the game I used to play, a botter can get caught out in the open, so they went back to their program to modify the code to add some kind of detection routine and then run it. When a GM comes in, they disconnect and stay disconnected until a set time that they can auto-reconnect to resume. This is where I had stated before that I often kept my forum and gaming matters separate. I was told of a cheating program by other players; little do they know that I was a forum moderator and a "spotter" for most GM assisted "strikes" that I wind up getting them banned after turning in real time capturing proof that they compared with their logs.
Will it go away? I won't think so because of this so-called "evolutionary" phase. However, if we can send them back packing they will think twice.
