What can you expect from this guide? Eventually, you may want to test your skills against less skilled players, even poor ones, without sugar-coating the truth. As others have done before, including myself, you can create a new alternate account and compete against unsuspecting players at or below the gold level. All fun and games, but eventually you will climb the rankings quickly and inevitably. So, what's next?
You have the answer, otherwise you wouldn't be here. You need to lose LP and demote in order to keep playing with less skilled players. However, this is a problem because Riot will try to identify your harmful actions, and your account might get banned or suspended for a long time. The key is to execute the plan cleverly with discretion so neither Riot nor other players detect it.
This technique is very harmful, yielding roughly a 90% likelihood of losing, but guarantees not being flagged by the buster system, which we can take advantage of due to its significant loopholes. Nonetheless, it is crucial to emphasize one important idea: "This means that even though Riot could take a few months to develop a heuristic to detect improper behavior, they choose not to." As a result, it's better to allow trolls to continue their behavior without interruption.
The system is intentionally flawed. The truth is, Riot is like any other business and prioritizes profit over strict rules. Obviously, they want to preserve their reputation. Hence, they use the buster system to identify inappropriate behavior, albeit in a rough and unsophisticated way. This is merely a facade to deter only the most noticeable actions.
When I began playing in season three, it was frequent to observe "smurfs" who roamed the central corridor and assisted the opposing team by allowing themselves to be eliminated by the opponent most likely securing victory to enemy team. It was obvious, and despite complaints, Riot took a long time to address it. Consequently, the accounts were later banned or suspended. Admittedly, it was too late, yet Riot has to prioritize its turnover as mentioned.
