Free is usually when someone is giving away a service/accounts for free.
Nulled means they are plugins that have been cracked by our devs, and costed money before cracked.
You kinda have to learn on your own, I could explain it but it would be a pain to write all of that here.
It would be best to google the command 'chmod' and what necessary permissions. Research and you can figure it out, it's easy.
Some plugins are asked to be removed by the plugin developers, so we put a paywall to push away those type of users.
Also some plugins are much harder to get and crack then others so a donation or two wouldn't hurt to help the crackers out.
Hi, try looking through your download's and finding the plugins you downloaded from BSMC. The files should have -CRACKED at the end of them, from there you need to find which plugins are on your server.
Take them all out of your server and add one at a time until you find the culprit.

Not sure about that being a feature in OTG, but I do know you can get a plugin to fill random chests with random items if that is something you're looking for.
Try looking into RLC.

Open DMs for ServerHound, did it send you a DM for instructions?
I am still new to this new bot so if it did not send anything, start a conversation with PacketRecieved/Hwiggy or moderators about it.
