So glad I found this thread. Indeed I tried the same to promote my website on reddit (no links attached), but it got immediately shadowbanned. I even did manual posting/comments from my machine to look like a real natural user.
I will share some of my findings which hopefully will help you:
- I did the same in January, using both my machine and some tools (which unfortunately doesn't exists anymore) to promote my business on reddit threads in niche specific subreddits. it worked pretty good, I was even boosting my comments with upvotes, but that got my 5 years old account with low-mid karma banned. Here I am sure it was because of the upvotes because even Reddit told me I was doing this.
- Then used that tool to add comments from different accounts, not mine. That worked slightly less, with more filters coming and filtering my comments.
- Then I got all my accounts banned/shadowbanned. Here I think for sure it was because I got my first account banned, my fingerprint got blacklisted.
- The most recent experiment of mine was to create a new account, same fingerprint, and decided to move slowly. I started even with scrolling and commenting relevantly to some threads, and when I wanted to promote myself, the comment was removed by reddit (literally this is what it has been seen on UI). Did some more non promotional comments, some were ok (did not get erase), some not. Another promotional comment. boom. shadowbanned.
At this point I hope it's just fingerprint issue, and not brand being blacklisted.
