Checklist

• I am sure the error is coming from Pyrofork's code and not elsewhere

• I ran pip3 install -U git+https://github.com/Mayuri-Chan/pyrofork and reproduced the issue using the latest development version

Description

I try to follow the steps to Sctackoverflow but I can't write a post with pyrofork tag because is not popular :-( so that is why I put it with pyrogram tag and I am putting here also:

I am using Pyrofork to send messages and I would like to know the differences between copy_message and forward_messages with parameter drop_author=True. My main usage is to backup so if the origin group is deleted or banned which one is better to not track from origin to backup group?

If in this case are the same which needs less resources or clock time?

I don't find anyone who is capable to explain the differences.

Steps to reproduce

1. send message with forward_messages
2. send message with copy_message
3. no difference noted

Yeah almost same, forward message just invoke ForwardMessages raw method and different with copy message that invoke different method. And forward message doesn't have parameter in copy_message, like has_spoiler.
