Where this comparison comes from

Public titles, descriptions and member counts from SubMouse’s SFW directory (see page date). Short rule titles and posting-activity samples SubMouse collected for both. Directory related-link mildlyinteresting → interestingasfuck. Rule lines are short titles only.

Members and public descriptions come from SubMouse's safe-for-work directory (as of 2026-11-02 UTC); 7-day growth measured from 2026-10-26. Posts/day and post-type mixes appear when we have an activity sample. Rule lines are short titles, not the full sidebar. Directory rank is listing order — communities outside the current Top 100 open in the info tool instead of a full community page.
