Once mentioned in Slack, then FP reported in uBlockOrigin/uAssets#8280 so improved with $match-case. So far no FP report in this version and I think it's worth being added to AG too.

@Yuki2718 Could you please show full URLs from tests?

[Yuki2718]

@Alex-302 Here new URL: https://regex101.com/r/YdVN2W/1

[Alex-302]

@ameshkov May we add it?

@Yuki2718 I've read the original issue, but I don't understand, why there's no $domain restriction? As I understand, it was tested on a limited number of websites anyway

[zloyden]

Maybe, there are many domains, but I prefer to use $domain for regex rules.
@Yuki2718 which sites need this rule? Please provide a list of them.

[Yuki2718]

@ameshkov @zloyden Because this is used by too many pirate sites, short links etc. and they change domain too often. URLs @ghajini listed were just a fraction, in fact animefenix is not included and, say, now in #84655 there are some more examples: https://regex101.com/r/YdVN2W/1 Lucky to me as I wanted to show (\?_=\d+)? part is necessary. If it's limited to certain domain, there's no need to add another regex - just add them to /^(?!.*(bootstrapcdn.com filter.

[ghajini]

Its used on so many sites i mentioned (check comments,not just main start comment)
