Well here's a few things to think about for everyone.

Server 1-10 are the original members of this game. Most of us have no desire to "cheat" or find cheats. And if any of us really found some serious cheat that gave us a seriously huge advantage, it would be noticed quickly, reported, taken seriously, and dealt with. SO we may not be completely in the loop on all the things happening on newer servers. Someone there may have gotten cheat engines to work with this game, or written scripts, or a bot etc. So we shouldn't just dismiss what newer people have to say simply because we don't know about it.

Now on the other hand, there are players out that who compared to others seem to be cheating and shouldn't just be accused of it with out serious proof.
If you have reported them to billing support repeatedly and nothing has been done to the player and they can still do the thing that you feel is cheating, then there are a few things to do.
1. Quit the game
2. move to a different server
3. do the same thing- but i would send a new ticket in asking if doing this would get your account banned or if it is considered in violation of TOS
4. GET LOTS AND LOTS AND LOTS OF Players to submit tickets about it. The most famous banning was on server 1 and it took dozens and dozens of players complaining to billing support for weeks to have action taken. Partly because it took billing support that long to gather enough evidence in their mind to prove beyond a shadow of a doubt the player violated TOS.

Player bans dont happen over night they take a while

Now in terms of getting the gold hero as soon as you unlock it from your title. That is possible without cheating, Ive seen it happen.
A 900+ score in lab is not unheard of, it is possible.
Getting lots of 800+ scores in lab is possible with a lot of luck


In terms of glitches being fixed - TONS have been fixed, and they will continue to fix them as they discover them and figure out how to recode it. It takes time.

Be patient. Be persistent Things do change in this game but not over night
