I have started using osbot's default drop handler because they have improved it. This script used to have another dropping style but the mouse handler was changed and rendered the drop style obsolete. I can, at best offer a nice dropping style which operates on item proximity rather than item slot recursion
I will work on the new drop handler right now, it will be better than the current one, but don't worry the current one isn't bad or good, since it is common way of dropping items.
For your account, I highly advise using mirror mode since you are VIP, as it eliminates client detection. Aside from that, just make sure not to look like a bot and don't too much and you'll be fine.
