Mara is a tool designed to quickly replace or front-run unconfirmed transactions by broadcasting competing ones. For the attacker, it’s effective and “safe” to use. For the victim, it means a real risk of losing funds if their transaction gets replaced before confirmation
basically Mara is one of several tools designed to do the same thing: quickly replace or front-run unconfirmed Bitcoin transactions by broadcasting competing transactions with higher fees.
What makes Mara notable is it’s often optimized for speed and automation, especially in the context of puzzle key cracking and mempool monitoring.
But fundamentally, it uses Bitcoin’s standard Replace-By-Fee (RBF) or mempool replacement rules—just like any other mempool?


?

Mara doesn't publish the public key. Without it, no bot will notice any ID txid , public key, or anything else. When the
origin address is 0, the all balance it's already in my new wallet

then in the mempool my transaction appears saying: Public key not available or not published

something like that
in short: bots are useless with Mara
