Did any regulator or launch site ban sniper bots, and did profits drop?

Research question: Have any regulators, exchanges, or launchpads (including Pump.fun) adopted rules, enforcement actions, or terms-of-service changes specifically targeting sniper bots or bot-driven launch front-running, and did those measures change measured sniper returns afterward?

The records show Pump's Terms of Use bar software or routine programs that interfere with normal platform operation, but the clause does not name sniper bots ¹. Pump's trading competition terms prohibit bots and scripts used to inflate a participant's score or trading activity, and all platform user-behavior rules also apply during competitions ²³. Pump reserves the right to change its terms without 14-day notice to address fraud or platform-integrity risks, but the records do not show that a sniper-specific change was made ⁴. Base's configuration changes and Flashblocks were reported to shift priority fees and select against probabilistic scanners, but these are network changes rather than sniper-specific rules, and none of the facts measure sniper returns before or after any measure ⁵⁶. The newest fact is dated 08 October 2026, so it is from early in the current month ¹⁴.
