Edit filter to prevent vandalism and harassment on userpages

An edit filter to prevent vandalism and harassment on userpages was implemented last year on English Wikipedia, and has been effective at preventing unconstructive editing. Briefly, the filter prevents edits on userpages from unregistered and very new editors. If your community could benefit from this filter, please review the documentation page on Meta for more information and implementation details. If the filter is implemented, please let us know on the project talk page. Thanks!
