Account is 2 months old. I'm using it with a fresh fingerprint (antidetect browser).Maybe the device you're using is flagged?
Also, have you tried posting in other smaller subreddits to see if your comment stick?
If the above aren't the cause, then probably Reddit started to limit fresh accounts until they get some age and/or browsing activity.
In this case, some subreddits are having non-disclosed age/karma requirements, and posts from accounts not meeting the criteria are automatically removed.Some subreddits work fine. Others comment gets shadowbanned.
what type of proxy where you using ? VPN / RESI / 4G ?Fresh account, fresh proxy.
I post a comment, it gets shadowbanned instantly (when I open an incognito tab it shows as "deleted").
Am I doing something wrong?
