He wrote the first viral post with 7k+ likes, someone asked what caused procrastination, then he replied with the long post, which I replied to. So there’s no reason for them to suspect that would be spam.
For myself these were my first two posts and I had a link in the second. I made my account almost a year ago, but even though posting a link in my second post does probably seem suspicious to a software system. creating accounts to post links is probably something spam accounts do often
