Bots that beat image CAPTCHAs often fail niche questions.</li> <li>Require email activation, or admin approval while the forum is small.</li> <li>Limit registration attempts per session.</li> </ul> <h2> For new members </h2> <ul> <li>Put new accounts in a "newly registered" group whose first few posts need approval.</li> <li>Block links and signatures until a member has a few approved posts.</li> <li>Don't let brand-new accounts send private messages.</li> </ul> <h2> Ongoing </h2> <ul> <li>Keep software and extensions updated; old versions are easy targets.</li> <li>Check the approval queue daily, and ban plus delete in one step.</li> <li>Watch for "sleeper" accounts that register, wait, then edit old posts to add links.</li> <li>Back up the database before bulk-deleting spam.</li> </ul> <h2> Don't </h2> <ul> <li>Leave registration fully open "just for launch."</li> <li>Rely on one measure.
