This likely will need a security review, unless it's used on at least one Wikimedia wiki. That being said, though the extension is tagged as unmaintained, that in and of itself is not necessarily a problem. This does seem to be a rather simple, uncomplicated, and benign extension, similar to a parser function extension. Additionally, I can see use cases on multiple wikis for local sysops to block spambots en masse, as an example.

@Dmehus ok.

The extension has not had any updates since 2014. Unless someone volunteers to rewrite the extension's internals, this extension won't work.

@Southparkfan @Dmehus perhaps the extension https://www.mediawiki.org/wiki/Extension:BlockAndNuke will work? its kind of similar to this one

if you can install this one that would work aswell... looks like there is a latest version of it 1.35
