Installing [[https://www.mediawiki.org/wiki/Extension:StopForumSpam|StopForumSpam]] is the standard first step recommended by [[https://www.mediawiki.org/wiki/Manual:Combating_spam|Manual:Combating spam]] for dealing with spam, which is one of the first problems owners of public MediaWiki instances are faced with. It should be part of the next MediaWiki release (probably 1.32 as it's too late for 1.31).
