Is the moderating team for sure. The mods of r/Brasil are also the admins of my lemmy instance and you can find pinned comments promoting lemmy on the subreddit.
Surely it's better that Lemmy is mostly found by those curious enough to go searching? The lower the effort required to get onboard, the lower the effort of posts that follow. Currently Lemmy has a bit of a Reddit-2006 vibe and that's far better. Quiet, true, but volume doesn't equal quality and sufficient volume certainly brings the attention of bots and shills.
I have blocked /u/safebot, lu/saferbot and /u/safestbot to avoid that problem of being banned on certain subreddits for the arbitrary reason such as posting in the “wrong place”.
