There is a must-read for all DevForum members in Exploiting Explained.
It all really depends on how motivated your attacker is - if you release your anti-exploit, it’ll broaden the chance a skilled exploiter will attack it and also releasing the source will make it easier to find countermeasures. (Though this definitely isn’t an argument for security via obscurity).
If you produce an anti-exploit, it’ll have either false positives, or it’ll be ineffective. If your anti-exploit has effects other than logging and monitoring, it’ll cause player annoyance (being teleported back if they do X action or Y action). It all ends up being a sum - is the user experience you produce by adding the countermeasure more annoying / widespread than if you let the exploiters do what they were doing? In many cases, the former is the truer.
Treat exploiters like mosquitos, not the diseases they cause. They can’t become a disease unless you open yourselves up to them past the baseline security Roblox supplies you. And a flamethrower tactic will probably kill the mosquito, but it might just kill you too.
