There I cannot help you. I have no control over changes to policy for this site, and honestly I don't follow things like this typically unless they affect me directly. But if you ask I'll be glad to check.
Server Specs currently has no controls over it, so it is dangerous to allow html, hence it has effectively been disabled.
When bbcode is allowed as an alternative, people still need to ensure they provide images that are within the requirements specified within the Rules & Regulations, not like the grossly oversize ones previously displayed, and they also need to be readable which is not the case in most that I still see displayed - remember, we ask for them to assist in problem solving, so they must be easily viewable.
Server specs (Server OS / Apache / MySQL / PHP / DragonflyCMS):
linux / apache 2.2.22 / mysqli 5.6.34 / 7.1.22 / 10.0.48.9418+
