The statistics are based on data from anti-spam service CleanTalk, for the period from April 2015 to March 2016. The analysis was conducted for the following CMS: WordPress, Joomla, 1C Bitrix, Drupal, phpBB3.0, phpBB3.1, IP.Board, SimpleMachines, MediaWiki.
The analysis was attended by all the POST requests processed by the service, such as comments, registration, contact forms, orders, feedback, and others.
The distribution of the main forms on the websites:

- Registration 53%
- Contacts 68.5%
- Other 45%
- Contact and comments 49%
- Contact and registration 21%
- Comments and registration 21%
Sites with:

Distribution of spam attacks per day on one site, with the division at CMS
Top of CMS on spam attacks
| CMS | The number of spam attacks |
| MediaWiki | 657.92 |
| Joomla | 172.45 |
| 1C Bitrix | 129.27 |
| Drupal | 118.14 |
| IP.Board | 98.70 |
| WordPress | 49.75 |
| SimpleMachines | 41.75 |
| phpBB 3.1 | 27.51 |
| phpBB 3.0 | 25.88 |
| Average | 146,82 |
As we can see, MediaWiki is very different from other CMS. In our opinion, such a substantial gap related to the fact that this CMS has no sufficiently effective means of protection and to track changes made in article for administrators is very difficult. This leads to the fact that it’s convenient for spammers place links in the articles.
The low proportion of spam on phpBB due to the rather low prevalence of this platform.

It should be noted that in October 2015, we launched SpamFireWall service, with a portion of spam attacks were blocked and they are not considered for the Anti-Spam service. It is also worth noting about SpamFireWall statistics as blocked not only POST requests, but all GET requests to the site.
As the graph shows, the amount of spam on web sites is only growing and has some seasonality. In the summer and autumn of spam growth stops or falls slightly, but with the onset of winter always starts growing.
The percentage of spam in the POST requests by CMS
| CMS | % of spam |
| MediaWiki | 99.76 |
| WordPress | 98.21 |
| Drupal | 96.08 |
| SimpleMachines | 95.74 |
| IP.Board | 91.72 |
| Joomla | 91.04 |
| phpBB 3.1 | 90.35 |
| 1C Bitrix | 82.03 |
| phpBB 3.0 | 81.87 |
| Average | 91,87 |
Statistics shows that the proportion of spam in the comments/registration/contacts, etc. greater than 90%. In our opinion, the spammers find promotion links are still working effectively and if not to advance in the search, then to attract audiences to the site of its resources.
