Periodically someone on Twitter will suggest that one of my Twitter accounts is a bot. Others will reply in the second person plural, suggesting that there’s a group of people behind one of the accounts. These accounts aren’t run by a bot or a committee, just me.
I do use software to schedule my tweets in advance. Most of the tweets from my personal account are live. Most of the tweets from my topic accounts are scheduled, though some are live. All replies are manual, not automated, and I don’t scrape content from anywhere.
Occasionally I read the responses to these accounts and sometimes I reply. But with over half a million followers (total, not unique) I don’t try to keep up with all the responses. If you’d like to contact me, you can do so here. That I do keep up with.
