YOu created your own bot? impressive haha
OK, I have not been on this discord so I can't say but I am guessing it should be similar to most of them out there
Some you have to apply to be in, they will review your posts and open the gates for you.
And then there are others like Adsactly that welcome you with open arms.
There are many discord groups out there, and you can find the banners/logos on many of the steemians post. At the end. Just click and it will take you there. And then it depends on what their terms are.
Now when on discord, you just need to chat, communicate with the other members. Let them get to know you as you get to know them. Just like at a party. The more people you know, the better the chances of getting a ride home... hahaha....
There will be channels for you to share your post.
And as you upvote theirs, they will upvote yours (hopefully - quality, interesting posts is obviously important too).
To search for someone, just put the "@" symbol before their handle .... for example if I wanted to look for you it would be https://steemit.com/@shafiqbhutta
Yes, you have to type in the full name without any mistakes ....

OK, try getting on adsactly first because that's open for anyone who is interested.
Try getting to know the other members :)
All the best and hang in there

It is true you came in for the rewards, but the some of the peeps here are pretty awesome
Get to know them :)
