It is not practical to expect tool developers to re-implement all of MediaWiki's anti-abuse abilities because that's just a ton of work, and a lot of those abilities require access to private material (e.g. Toolforge tools do not have access to users' IP addresses, so no way to check against IP blocks).
As some tools are repeatedly being abused for vandalism, we intend to expose the OAuth consumer ID as an AbuseFilter variable (oauth_consumer). This will allow wiki admins more flexibility in designing and writing rules depending on the tool in question. Please be careful when writing these kinds of rules, as many tools are intended to be used by newcomers at workshops, hackathons, etc. Blocking a tool outright, while it might stop abuse in the short-term, is more likely to be detrimental to your wiki in the long run.
