These new posters have just joined, and have made only a few posts each, every post in a different thread. Each post is brief, and appears to be out of context -- almost as if a paragraph has been lifted automatically from some PRIOR post.
So far, the ones I've spotted have not replied back to any responses they get -- e.g., asking for more information re their apparently out of context post.
AND, each of their posts ends with an IMG tag trying to include a 1-pixel image file using a short form URL. Such 1-pixel images are typically used as advertising tracking tools.
Just a heads up that there may be some automated account creation and random posting going on here, for reasons unknown. And if that's not it -- if these really are real people who just happen to be doing the same type of confusing posts by coincidence -- the 1-pixel (tracking?) files are still suspicious in their own right.
