Using all caps

Do not do the following:
1.1.10. Use or post topic/thread titles or content which is fully capitalised, contains unclear abbreviations, contains or suggests profanity, or does not properly indicate the content of the post.

The rules are pinned and visible for everyone since years.
If you do not like this specific one, no one force you to post on our Discussion Board. I am pretty sure you will be able to find a place, where posting in caps is totally ok.
Good luck discussing there!
