"Anti-Lag" Scripts, do they actually work or are they the problem?

Considering that they are a hoax, they could be doing about anything.

I decided to look at some decently used(139 takes) 'anti-lag' script and it simply set debris.MaxItems to some arbitrary number. Note that the MaxItems property is deprecated by now.

This example wasn't too bad, but more than often they might be harmful to the place, since they are designed for people who aren't too well with scripting and won't understand what they actually do.

So in the end those scripts won't decrease lag, but have high chance of increasing it instead.
