Spend a few days using Reddit normally. This doesn't need to be torture, find a few small subreddits with a niche interest (there are tons of good tech subs) and just make a couple comments each day. That's all it'll take for your account to not be automatically flagged in most places. It could take 10 days, but assuming you're not getting downvoted that should be enough.
