To be fair, I haven't hosted a drop, nor do I have insight into how they are configured by the developer, but I have noticed a common frustration among other users. For drops which are streamer specific and not open to general, the user still sees text such as the following-

"To continue the progress, go to a participating live channel including /oniyadayo, /vodkavdk, /tw_rapid, /restiafps, and /berbatow"

"Go to a participating live channel, including おにや, ボドカさん, 瑞皮, restiafps, Berbatow, and more"

Where in the first example, "participating live channel," is a link to "https://www.twitch.tv/directory/category/apex-legends"

and in the second example, "more," is a link to "https://www.twitch.tv/directory/category/apex-legends?filter=drops"

In the case of a drop not open to general, neither of these links provides a list of channels including only channels with drops enabled for that campaign. One list is everyone streaming the game, and the other uses a filter which appears to be misused.

In the case of a drop open to general, these links still do not show a list which includes only channels with drops enabled. Users must open the stream to see if the notification pops up for the drop, because streamers commonly put the tag, "Drops [Enabled]," or similar, when they are not.

This adds a lot of friction for users looking for drops, and a means for streamers to abuse the drops campaign feature to attract viewers. What I would propose is that both of these links run a query against some internal value which truly indicates that the drop is active, and is uneditable to channel owners.
