I was reading comments of this topic https://bitcointalk.org/index.php?topic=4490532.0 ==> Captcha
Then I was reading the comments of this topic too https://bitcointalk.org/index.php?topic=2645450.0 ==> List of Accounts which Needs a Ban [ICO pumping accounts]

It's easier to spam when a bot or a user do not need to spend much time on resolving a Captcha.

How about we think of adding a new feature?
Add captcha before posting in a topic and also before creating a topic.

Personally I would not like it but for the sake of keeping the forum a bit safer from these bot activities, I will gladly accept it. I would like to read your views.
