I noticed them both also I thought they saw some other new members asking about big builds and smelt blood in the water.There were several posts from 2 different new people that were like this, very much looks like AI dispensing bad information or advertising. I reported both. And I also reported a third that was a 1 post wonder of "look at this" with a link to some product or other on youtube that was scraping hit/view count.
I gave this one the benefit of the doubt and advised him to change his profile photo(advertisement) and to read the forum rules but he never messaged back and went on to play forum bingo, so as I got no reply or thanks I went into troll mode.
