How to reduce comment spam on WordPress blog?

Hello dear, I have problems with some spam bots, the administrator of my hosting recommended disable allow html code in the comments, how could I?

To combat spam bots it is recommended to do the following things:

  1. Install and configure Akismet
  2. Hide what HTML tags can be used for comments
.form-allowed-tags {
    display: none;
}
  1. Use some plugin to disable html input in comments section (not the best thing to do)
  2. Install captcha or some other spam prevention tool. Like custom forms or other.

Personally, I think that the best option is to use Jetpack comment system or even Disqus. You will see much, much less spam by using these plugins.
