The truth is, this issue is more complex than it seems, the most popular marketplaces for buying accounts are accsmarket, G2G, and ***, the first offers accounts ranging from very cheap to more expensive options, while the others usually offer profiles with more details, such as exact age and karma listed separately.
However, buying is only half the battle, the real headache begins later, when you try to use them without getting banned, many of these cheap accounts come with a shady history or were created in batches using the same IPs, if you connect from your regular browser, reddit detects something suspicious immediately, the key is to use an isolated environment, like an anti detection browser, to give each account its own clean digital identity.
Don't go crazy posting links on the first day, purchased accounts need a warm up, spend a few days browsing, upvoting, and commenting on simple things in large, relaxed communities, if you burn them too quickly, the algorithm will silence you without warning, and that's the end of your money, the trick is to appear like a real human, not a robot desperate to sell.
