As you are aware of the bots being made for account creations of social media,why do they produce lower quality accounts if they can spoof user agent,browsers and bypass everything to make it look like a normal user?
Also do you think the quality of IP plays a role here?
How do they exactly track because softwares produce lower quality accounts and manually made ones,they produce higher quality always.Why is this the case other than the reason that IP plays a big role here?
Great question! This happens for a few reasons.
1. Most people do the minimum.
When writing code to bypass or obfuscate something, most people will be happy if it works, then stop. While they can fine tune their software, most don't so long as it works and they can sell it. This happens in most companies, regardless of the product. This is why security usually takes a backbone and is only handled AFTER something happens. Devs teams get pushed with deadlines, and when they provide the option to release tomorrow, or spend a few weeks testing for security, managers always say, let's get it out as quickly as possible. Leads to many holes in security, but in this discussion, it means people will just write tools to trick social media platform algorithms but won't make it as 'good' as it could be. But MORESO, is that social media platforms have the budgets and a massive amount of data to determine what's considered 'fake' and what isn't.
The biggest social media platforms can use industry-level Machine Learning, or some confuse it with "AI", and can find outliers a lot easier. Or they can just pay another company to handle it for them, and give them the analytics. Never impossible to trick a system, but it takes more work.
2. IPs do play a big role here. I can't say the weight of IPs in their algorithm, but it definitely plays a vital role. People selling RDP access, and possibly proxy sellers, can provide more insight on this than I, but depending on location, and the type of IP, depends on how the website or social media platform will treat you traffic. Some websites don't allow any VPN or proxy users and block them immediately. Some only allow 'residential' IPs, and some block by country.
I'm using a pirated copy of Win 7 right now and I'm not upgrading to anything despite of any of so-called experts' advice. I don't give a shit. If you're such a good hacker go on and hack into my system, and see how much I care... that you steal all of my porn LOL, GTFO with that big advice like update your windows, create quality content and all that bullshit
You think of me as an 'expert'? how sweet.

I really don't care what OS you run. It's your shit, not mine.
Why aren't hackers targeting internet marketers? It would certainly be the most profitable ones to target?
They do, but idk if they're the most profitable. The recent types of attack include ransomware. It's been easier for hackers to, let's say write some worm that can infect people like
@monere who run outdated OS, encrypted all their data, and sell them a decryption key like $100. It's a numbers game, so if you target a few million systems, and even if only 1% pays $100, you'll make a good chunk of change. More sophisticated hackers will turn these into botnets and sell access to them....like IPs and Proxies. But it's a lot to manage such a business and is difficult to keep up. Takes a lot of work, knowledge, and skill.
Other things people can do is dump bitcoin. Or collect PII from these machines, then sell that. Credit card info as well. There's a million ways to make a million dollars. Some people have very valuable information on their computers. Some just have 100GB of porn.
