| 5 | The XWiki project offers several solutions to help fight spam. These are especially useful when XWiki is used as a public site. | ||
| 6 | |||
| 7 | = CAPTCHA = | ||
| 8 | |||
| 9 | You can enable [[Captchas>>https://en.wikipedia.org/wiki/CAPTCHA]] both on the [[registration screen>>extensions:Extension.Administration Application||anchor="HActivatingcaptchas"]] and for [[comments>>extensions:Extension.Administration Application||anchor="HRights"]]. | ||
| 10 | |||
| 11 | You can also use the [[XWiki Catpcha module>>extensions:Extension.Captcha Module]] if you need a tighter integration in your own wiki pages / wiki application. | ||
| 12 | |||
| 13 | = Notifications = | ||
| 14 | |||
| 15 | You can choose to be [[informed by mail>>extensions:Extension.Watchlist Application]] (even in real time) about changes done to your wiki, and thus be able to quickly revert spam. | ||
| 16 | |||
| 17 | You can also install the [[IRC Bot Application>>extensions:Extension.IRC Bot Application]] to get instant IRC notifications when a page in the wiki is modified. | ||
| 18 | |||
| 19 | = Delayed Indexing = | ||
| 20 | |||
| 21 | You can implement [[Delayed Indexing>>http://c2.com/cgi/wiki?DelayedIndexing]] to discourage spammers. It tells search engines to not index pages that were recently updated. On an active wiki, spam will be removed very quickly by community members. Once a page has not been edited for a while, you can assume the community approves of the pages content and thus is spam-free. | ||
| 22 | |||
| 23 | This can be achieved by editing the "HTTP META INFO" section of the [["Page Element" Administration section>>extensions:Extension.Administration Application||anchor="HPageElements"]]. For example you could decide to wait 5 hours after a page has been created before allowing it to be indexed by using: | ||
| 24 | |||
| 25 | {{code}} | ||
| 26 | #if ($datetool.getDate().time - $doc.getCreationDate().time < 5*24*60*60*1000) | ||
| 27 | <meta name=“robots” content=“noindex,nofollow” /> | ||
| 28 | #end | ||
| 29 | {{/code}} | ||
| 30 | |||
| 31 | = AntiSpam Application = | ||
| 32 | |||
| 33 | Last but not least, you could install the [[AntiSpam Application>>extensions:Extension.AntiSpam Tool Application]] which provides 2 main features: | ||
| 34 | * Ability to prevent spam from being entered (by filtering on keywords) | ||
| 35 | * UI to easily remove spam content and all content entered by some given user |
