Which CMS spam more often?
The statistics is based on data from the antispam service CleanTalk , for the period from April 2015 to March 2016. The analysis was conducted on the following CMS: WordPress, Joomla, 1C Bitrix, Drupal, phpBB3.0, phpBB3.1, IP.Board, SimpleMachines, MediaWiki.
All POST requests processed by the service, such as comments, registrations, contact forms, orders, feedback and others, took part in the analysis.
Comments 65.5% of sites
Registration 53%
Contacts 68.5%
Other 45%
')
Contacts and comments 49%
Contact and registration 21%
Comments and Registrations 21%
Sites with:
1 form 23%
2 forms 34%
3 forms and more than 41%
As we can see, MediaWiki is very different from the rest of the CMS. In our opinion, such a significant gap is due to the fact that for this CMS there are no sufficiently effective remedies, and it is very difficult for administrators to track changes made to articles. This leads to the fact that spammers are convenient to place links in articles.
The low proportion of spam on phpBB is due to the relatively low prevalence of this platform.
It should be noted that in October 2015 we launched the SpamFireWall service, with some of the spam attacks blocked by them and not counted for the Anti-Spam service. It is also worth noting about SpamFireWall statistics, since not only POST requests are blocked, but also all GET requests to the site.
As can be seen from the graph, the number of spam on web sites is only growing and has some seasonality. In the summer and autumn, the growth of spam stops, or slightly decreases, but with the onset of winter, growth always begins.
Statistics show that the proportion of spam in the comments / registration / contacts, etc. exceeds 90%. In our opinion, spammers consider promotion links to be still effective, and if not to advance in search, then to attract the site’s audience to their resources.
