The flag doesn't work? Maybe it's weekend?
If the same person flags a few times in comments and reviews, it works normally, but there's a waiting time.
I did it when I saw advertising on the channels I'm responsible for a few times a day and the next day, it normally disappears.
I don't bother answer to bots, it's bots.
I don't delete comments when ppl ask for subs, I don't know which category it fits in and I sometimes reply to explain or to tell them that they are volunteers working on it, so at least ppl who want to ask again already have an answer and don't ask again (but some feel the need to ask multiple times to show that they are indeed many ppl waiting to hurry volunteers or kind of pressure them?).
I understand that many don't know how it works so they feel it might be given up or they're just being impatient so they just ask out of ignorance or impatience.
Also, they will just continue to ask and we can't control this type of thing on every channel or every episode.
Don't take it personally or don't feel annoyed over this, you do what you can and you know what you do. But they don't know the inner problems.
So just explain so they know that there was an urgent event life happening to one subber or don't take it personally.
Also, I have seen that some people who comment everyday end to send a message to the Cm asking or complaining.
I answer so they have the explanation of their waiting and I also give them an alternative: there are so many dramas out there with full subs that need to be discovered that it's pity that they waste time on waiting for subs. I mean viewers should use their time wisely and not wait for subs on a unfinished product that is in the state of being built.
In these pm exchanges, I could pass the message more easily and they don't spam in comments anymore because I feel they have understood how it worked and why they wait (I hope so).
There's nothing wrong in waiting for subs, because the videos have yet to be subbed compared to some other websites.
There's nothing wrong in waiting for subs, it's done by volunteers, no one can predict events of life or the timetable or the mood of a volunteer.
Once you know what is right and wrong, no need to feel over concerned by that.
Flag and push it at the bottom of your priority list.
