We don't even allow those sources here, so yes. That bad.
"Trinity-based source modifications - Foreign modifications (modifications to the source from other programmers outside of Elitepvpers) are not permitted. They have been found to contain keyloggers and heavy performance problems, and are very unstable. Elitepvpers has the original, unmodified sources available, as well as more stable sources by other authors. Please use one that we provide here to avoid these problems."
