[Psych_O]

На MaxCheaters почти всегда говно толкает, форум чем то похож на ксла2.

Борьба с ботами , это погоня за призраком. Проблемы должны решатся на уровне экономике сервера , а цены на предметы формируют сами игроки(по этому там и нет ГМ шопа). Проблемы хаков , багов решаются на уровне сервера.
Я писал и капчи и защиты , опыт говорит только об одном - все это х*я

Ну и под конец выложу алгоритм генерации капчи, не требует ни каких картинок встраивать в клиент , передается как клановый значек , работает безотказно.
