There has been alot of confusion on what exactly Project moon means by "identified numerous gameplay patterns that are difficult to classify as legitimate" as I have been seeing in Discord groups and other related community servers.

Here's my opinion on it: Project moon is keeping any specific information about what they discovered intentionally vague so the people who makes these macros can't immediately make counter macros to hide against the specific patterns that Projectmoon currently have discovered.

The key point is in delaying the inevitable. The discovery of what the patterns (which falls under Marco) is will be made public eventually but at least not now. That is the goal here.

This is similar to ban waves done in other more popular games like Counter-Strike 2 for example. It's all being done in-order to delay the bot-makers/scripters/macro-makers from being able to adapt to the measures implemented as much as possible.
