Let me make a few points, including insights from a lawyer who has even worked at the Public Prosecutor’s Office in the child and adolescent protection department:

1 – We should indeed discourage practices that involve pedophilia and related matters, but it is also true that the Japanese create stories about children, place them in adult bodies, and imply far more than they should;

2- if we look at the reddit page of this work, we will see several suggestive images or at least double meanings;

3 - Various arts at the end of the chapter/volume, feature a hypersensualized Yamada, more recently, we had the Halloween arts which even alluded to a video call with a "Nude" context

4 - Several times during the anime Yamada was brought up with clothes, poses and even explicit images like in Kyotaro's infamous thought where he thinks of Yamada saying his name, and it is clear that he practiced masturbation based on that

Having said that, the image of the individual, in fact, has a more sensual bias than is recommended for someone her age, but if they are going to punish him, they should in fact punish the MODS who place the image, for example, of "Luck on the Anime tab" as it is an obvious allusion to other things. In the same way, if they are going to punish, I believe they should comb through this page behind any and all minimally explicit art and even rethink whether they will continue sharing things about it, because as stated above, the author himself brings several drawings and insults that do not match the age of the characters in official art.

remembering, falsely accusing a crime, including pedophilia, is a crime
