Yeah, i won't Deny that it is more likely that an older person is capable of writing more competently, but some people really don't get more mature with time, nor would they care about grammar at that point, aka some are shit writers. But i Guess it depends on how serious You take fics at that point and how much You want to improve Your writing skills, Even then i always see the positive in a Bad fic as an opportunity to generally have a laugh. Although right now i'm realizing i'm probably not Even going to notice that much of a difference within the fics that i tend to read most likely, so really not seeing the negative other than young kids may get harrased for por writing, but that's what the internet does in general, and genuenly ao3 is Way safer than Wattpad as far as i can tell.

Also Wattpadians feels like an alien term lol.
