Well, Fluent has well over 1.6k subs and will probably not have a problem (no idea if he gets past the hours watched criteria) Also can't imagine that a shoutout for a german Channel there has that much use either.
I think the scenario you are mentioning is working more for people who immediately get 10000 views or so with each video. If one of my videos gets 100 views after a couple of days I am happy.
I could "mobilize" like 3-5 viewers at most (and fluent doesn't even need them).
Kordanor,
Do you put English subtitles on your videos? If you don't, are you planning to do that? You have some really good videos covering games which I play / I could possibly play. I'm asking because I know sh_t of German tongue and since I don't mind reading English subtitles (I even watched Netflix's Dark series in original language - of course with Portuguese subtitles), if you do so I can happily subscribe your Youtube channels.
