Twitter may have put the kaibosh on this now, or maybe I'm doing it wrong. Got a test account deactivated for botting; I can reactivate it using my SIM but it only took a few hours to go down.
I used one PVA account, which I'd used for just under 2 days to age it a bit. I retweeted big accounts every half hour or so and followed their followers at a rate of 2-3 followers every 5 mins, taking 15 mins break every hour.
I wasn't sure about the wording of the liking tweets part, but I liked 10 tweets over a span of fifteen minutes, based on 10 different keywords, and then took a 10 minute break before starting the cycle again.
I had a bit.ly shortened link to a landing page which contained a shortened affiliate link.
Hadn't gotten around to tweeting my affiliate link.
Like I say, it got shut down within hours, so possibly this method needs a new twist or possibly I did it wrong.
