I don't think the spam situation is that serious. I've only ever seen two unreaped spam nodes on perlmonks, because the editors delete them quite fast.

Spam in most sections (SOPW, Med, PMDiscuss, Obfu, Poetry, CUFP, Snippets, Code, and News) are hidden by the approval system. Posting Categorized Questions is allowed only for monks of a certain level, Polls only for a certain group, and sections such as SiteDoc don't have an automatically generated index. I don't know how Book Reviews, Module Reviews, and Tutorials are moderated, but if the posts immediately show up in the section, then that's why there can be spam.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
