Okay, I have massive anxiety about reporting people, but I have a problem. So many people use various colors with absolutely no background. Now, I'm using a skin with a grey background, and just about every color blinds me. I know this is against the rules, but I see so many people breaking this specific rule I don't know what to do. I think I've asked a similar question, but I keep forgetting the answer. With so many people breaking the color rule, should I send one message to a Moderator and say "this is a list and proof of people using colors without backgrounds" or just report them individually? If individually, should I report them with a day in-between each report—so that I'm not reporting too much? I wouldn't want to bombard the staff with massive amounts of reports.
