Here is what happens:
1.
Not all accounts get captcha. Mine is really old, botting a hell much time and nothing
2. If an account has no captcha and gets banned (
Stage2) for botting, a pernament captcha will apear from now on to be sure you won't do it again.
3. If an account with captcha gets banned (
Stage2) for botting, nothing changes about captcha
4. All those who get
Stage2 get banned for 1 day and loose some massive EXP and Honor.
Stage1 - pernament ban. Appears after getting a second ban (getting ban after you are in Stage2)
