Good advice in this thread overall. I would take a few things into account:
- Good hardware, ideally you're using a real phone, not a cloud phone or antidetect browser. People claim it works, and it might, but its just safer if you don't mess around
- Don't use catchall domains or weird providers. Stick to GMails/iClouds (aka what normal people use)
- Use a mobile proxy or an ISP proxy. Mobile proxy is best, esp since if you use a real phone. You can find a good one in this forum
- Don't sign up and instantly start posting/commenting etc. Most people who sign up to Reddit are usually doing it because they want to join a specific community or read/research something. Most people on Reddit lurk, rather than post, especially at the beginning. But you should do the same, join a few communities, lurk around a bit, upvote/downvote, slowly ramp up activity. Don't try to karma farm or make a lot of posts soon.
The social media game is about being patient and sticking it out and making long term decisions that compound over short term fast wins.
