Describe the issue

This is somewhat related to https://forums.lanik.us/viewtopic.php?f=64&t=43113, but I now have an additional example and a decent-ish solution:

When pasting certain links into Discord channels/chats, their embed images fail to load due to generic blocking rules in various lists (Usually EasyList).

• Example 1: Paste https://adguard.com/en/adguard-windows/overview.html (Image fails to load due to /adguard.$domain=~adguard.com|~adguard.mobi|~adguard.oneskyapp.com|~greinr.com in EasyList).
• Example 2: Paste https://www.ispot.tv/ad/7Jao/lactaid-milk-dont-forget-the-milk (Image fails to load due to .net/ad/$image in EasyList; the link leads to what seems to be an online video site and therefore does not need to be code-bracketed.)

The solution I propose for Discord only: @@||discordapp.net$image,domain=discordapp.com

Notes

I was not able to get @@||discordapp.com$generichide to work, and I was not personally able to figure out why.

I could not see any existing blocking rules in EasyList, uAssets Base or AdGuard Base that targeted Discord images of any kind, so I presume it's okay to whitelist discordapp.net as a whole.

Additionally, it seems that .net/ad/$image caused problems with the video suggestions on iSpot as well, such that I propose adding @@||.cloudfront.net/ad/$image,domain=ispot.tv as well:

@@||discordapp.com^$generichide
works fine on my end.

Can you point me to those video suggestions?

@@||discordapp.com^$generichide works fine on my end.

Ah, okay. I'll take your word for it, then.

Can you point me to those video suggestions?

They should be beneath the video information values, marked in orange in this screencap:

direct links?

[DandelionSprout]

Presuming you're talking about iSpot (Example link is the same as in the Discord part of the issue report), I believe they probably serve as direct links, but that images are supposed to show up above the grey links. Here's how the oranged part above (and apparently also the Screenshots section) looks like with @@||.cloudfront.net/ad/$image,domain=ispot.tv:

or:

@@||cloudfront.net/ad/*-small-*$image,domain=ispot.tv
@@||cloudfront.net/img/events/event-placeholder.png$image,domain=ispot.tv

if no EasyList block "big" photos?

[okiehsch]

I don't use discordapp, can you narrow the exception or is that not possible?
What are the requests blocked in your examples 1 and 2.

IMO similar should safe ❓

@okiehsch NO... works:

/adguard.$domain=~adguard.com|~adguard.mobi|~adguard.oneskyapp.com|~greinr.com,badfilter
/adguard.$domain=~adguard.com|~adguard.mobi|~adguard.oneskyapp.com|~greinr.com|~discordapp.net|~discordapp.com

maybe wrong used badfilter?

IMO discord no have ads, so we can add exception or on EasyList:

@@||discordapp.net/external/*/img$image,domain=discordapp.com

[okiehsch]

@@||discordapp.net/external/*/img$image,domain=discordapp.com
won't work for Example 2 or am I missing something?

[krystian3w]

I see..., /img/ is from AdGuard URL only.

@@||discordapp.net/external/*$image,domain=discordapp.com

[krystian3w]

EasyList use both method fix if you analize filters.

The only explanation is the size of the letters in the url... Or it's hard to find the logic that allowed one script to pass, not the entire domain.
