The best response is to stay calm and avoid immediately assuming the worst. Simply pick it up, throw it away, and clean the area if necessary. An ordinary object does not have any special power over you simply because someone online has given it a mysterious meaning.
If you repeatedly find unusual objects around your home and genuinely believe someone is intentionally leaving them there, focus on practical precautions instead of superstition. Keep entrances well-lit, maintain reasonable boundaries, and pay attention to any real signs of unwanted activity.
Ultimately, a tea bag on your doorstep is most likely just a forgotten or misplaced object. Sometimes the simplest explanation really is the right one, and there is no need to let internet folklore turn a harmless discovery into something frightening.
