Club and profile background: A visual disturbance, and a few suggestions

It's a good idea to disable the club background (and even my own profile background) if the dark UI is enabled.

Honestly, this is the exact reason I rarely visit any club page (even the rare clubs to which I belong) - as far as I can tell, ALL of them have background images that make the pages unreadable.

I heard of a high ranking club whose owner/admin said to one member who complained about this, 'It's a you problem, nobody else has this problem.' Just because nobody else complained yet doesn't mean the argument of readability is invalid. And they didn't ask the members either if they think that the background is too much.

I made my background just a solid colour that fits with the theme and makes it easy to read.
Solid colours are usually the best option for background. But sometimes people use blue, that messes up with the naturally blue texts of the site. Naturally blue texts are - hyperlinks, mentions etc.
(The main version of it was published in the official club 'Club Admins'. I am re-posting it to raise awareness.
You will find the suggestions at the end of this post.)
Some clubs and profiles like to add background to their clubs. But it makes the letters in foreground difficult to read in Dark UI. Perhaps they use Light UI themselves. Even in light UI, the image parts in between the white boxes cause visual noise.
But both Light UI and those backgrounds hurt the eyes. If there was no Dark UI, I wouldn't use this website at all.
Most of the backgrounds are nothing but visual disturbances. Some people post a picture so that the whitish font is readable, but then forget to check if it is readable while scrolling up & down, and if every font colour is suitable with it, blue (for links and mentions), dark grey, black etc.
The default background colour of this site is very nice. It is a soft colour, yet dark, the font colour is not white yet nicely readable. Overall it suits the vision. So this default setting is perfect and enough. Too much decoration spoils things.
People who set club and profile background maybe see things differently. So for everyone to see, I am presenting about 40-50 screenshots as example. Judge by yourself if any of these is vision comforting and script readable at all.
These ones are even animated, makes me dizzy -

Now some profile backgrounds -
This one was animated -
*** This is a good background, eye comforting -
The suggestions, to the developers of this site:
Remove the option for club background altogether.
If you must keep it, don't allow to upload pictures for club background. Give some options of preset wallpapers. Those preset wallpapers should be as eye soothing as the present Dark UI.
Additionally, keep an option for users to propose a wallpaper to be set as club background. A developer will judge the visual comfort of the proposed wallpaper and then will allow or reject it.
Finally, a balanced option is this: If a user chooses Dark UI, then among other things, he will not see any club-background, tournament-background (automatically fetched from a club), or profile-background (individual) at all. Dark UI is chosen because it is comfortable to the eye. That aim of eye comfort determines that users with Dark UI option won't see any background in club, tournament, or profile.
(If you agree with me that something needs to done about club-, tournament-, and profile-backgrounds, then write 'I agree' or something similar in the comments. Any other suggestion is welcome.)
