Lemmy.ml, like lemmygrad.ml and hexbear.net, has consistently been accused of improper Federation practices and many instances have decided to ban one or both of the latter by default, with many individual users having already gone further to block the former as well. However, many individual users on lemmy.ml seem unaware of the accusations of the practices of their admins, and some people go so far as to see lemmy.ml as a sort of default instance on the Fediverse.
This discussion promotes wider knowledge of the situation and what might be done about it in the future, in order to e.g. not turn away new potential Federation members (Fedizens?:-) that could otherwise associate what happens on that instance as something relating to the Fediverse as a whole.
Which is why all the instances I recommended you have a large number of users (lemm.ee even has more monthly active users than lemmy.ml: https://fedidb.org/software/lemmy/)
