Can I use my own accounts for activity in threads where I bought comments from you?

Only if you’re using accounts that are indistinguishable from real accounts, like ours. You must also use good texts, which can’t be easily identified as “shilling”.

You won’t get this necessary level of quality when buying comments from “Pakistani farmers”. For this reason, you’ll be putting your post and our accounts at risk, therefore when we detect such activity we stop working in that particular thread immediately, and we might even delete the comments already posted by us.

The above also applies to BitcoinTalk bumps.
