To be fair, I've seen content from here and other Telegram channels in that same channel, and it doesn't bother me.
In fact, I think it's good that there are backups of content that, frankly, I don't want to re-upload because of its enormous size.
Besides, I've seen that the Chinese Telegram channel, where things like cards, SD cards, or coordinates are rarely shared, also contributes to what's distributed; like the infamous Unagi cards.
