### 󠀁[Decent Captcha plugin – free version works well](https://wordpress.org/support/topic/decent-captcha-plugin-free-version-works-well/)󠁿

It’s a good plugin, works with little setup needed. Chose arithmetical captcha and
only drawback is some of the maths is too hard for me to work out (to be honest,
more a problem with my mental arithmetic rather than a problem with the plugin!)
You can choose several options even in the free version and this has worked well
to protect my site. Very happy overall.

It slows my backend work very much. Practically I couldn’t work on posts, on updated
posts, or update plugin. I had to do much, much work to discover which plugin creates
annoying loading, loading pages till it’s giving 524. Interesting that the front
of the site works well.
