Growing new personal account

Thing is, I used to have a decent-ish account karma-wise, but I made an unwise mistake of logging on with the same IP i used for accessing work accounts (I used to work in a small games publisher, was managing games' accounts on social media) so my main account got perma banned and appeal was reject. Even though I was not using said account for anything other than personal use.

So I want to start a new one and I wanted to ask - beside coming up with ideas for subreddit-specific content (which I used to do on occasion), is there any recommendations or specific places where one can relatively fast get karma?

If something similar was already disscussed - please do point me to the thread.

Don't reuse other people content they have idiots on there that will flag your account for karma farming and vote manipulation.

You can repost content on popular subreddits for quick post karma, you can also buy upvotes to accelerate the process.

Sorry for getting back with an answer later than I expected.

Thanks for the feedback, I will keep all the suggestions in mind as I've just created the new account
