lack of important tags on fics

so I just read this really good janka fic, but it ended up having them aged DOWN and having sex but THERE WAS NO TAGS ABOUT THIS AT ALL!!?? ABSOLUTELY NOTHING and I have never been more pissed. I wasted my fucking night(it’s 3:30 am rn) reading what I thought was a peak fic but just ended up being cp and it’s not tagged. Im so mad CAN WE PLEASE TAG OUR FICS CORRECTLY GUYS. They are so lucky it’s a weekend right now, if I was late to school because of this I don’t even know what I would do but I would be extremely angry.
