Question issue: Max Links in message not count some link correctly

Links are not count in some cases.
Even when setting 'Max Links in message' = 0, link into html code are not count and allows to post spam.

For example :
<a href=https://test.com/>non stopped spam new spam
or
<a href=https://test.com/>non stopped spam 2 new spam 2

Can be posted event when 'Max Links in message' = 0

Please create a configuration report: docs.kunena.org/en/faq/configuration-report
I can't reproduce this error. Kunena uses BBCodes not html codes.

The issue is not where using bbcode, but when the 'spammer' is using directly html inluding link.

It's not possible to add working links with html codes. See here: <a href=https://www.kunena.org/>Kunena
But maybe I did not understand your problem correctly.

Yes, I know it's non working link (for click) for the final user, but it's spam content with link (even if not working).

In this case are the links not the general problem, but the spam users. The registration is handled by Joomla, and when you allow to register, you can never prevent, that spam users register in your page.
It can be helpfull, if you set in the configuration (tab security) Moderate New Users = 1. Then must a moderator approve the first message. Is it spam and a moderator not approve this message, so can this user also not publish his next message.
The problem in this case is only, a Mod or Admin must for all new users approve the first message.

Even if the code is not working (not 'clickable') the link with a part of the html code can be added into the post (usually it's a spam).
1/ It will be nice to be able to take into account all link (working, not working, html, text ...), may be with an option.
2/ It will be nice also to be able to configure 0 (real zero) for the 'Max link in message', because 0 = unlimited today.
1+2/ The top will be to be able to have the real 0 and take into account all type of url (working or not) working together.Thank you in advance
