XF 1.5 Is it possible to stop new members posting images or embedding media?

There's a periodic problem of new members joining to post a link to their YouTube site, or embedding images, as a form of self-promotion.

Is there an automatic way to prevent them from doing so?

 

Cheers for replying. Would have loved a simple way to do this by post count, rather than have to create a new user group which may seem a little too restrictive.

 

I suggest using the First Post Email v1.5 add-on:

https://xenforo.com/community/resources/first-post-email.3343/

This will alert an admin or moderators of the new members first post. This can help in two ways:

1) A speedy reply to the first post is good if coming from a non-spammer.
2) If spam is contained in the post, delete post and the spammer account.
