It depends on what you mean by "personal". When some users say "personal" they simply mean a wiki intended for a topic of their own creation. Others mean a place for them and their friends to get together. Both types of wikis are allowed. What is not allowed are wikis with restricted editing (i.e. where only certain users can edit). If this is the type of wiki you want, then you could consider using either ShoutWiki or Miraheze.

For a slightly more lengthy description of the various business models (with examples), see this post.
