New bumping group. After Rikafip published a post (https://bitcointalk.org/index.php?topic=5237690.0), all accounts stopped activity and the threads where they wrote comments were quiet, but not for long. In the threads of IndexChain, Relictum, and a few others, I noticed suspicious activity. Below in the table you will see the activity of these accounts. Almost all accounts write in the same threads.
Also Merit, which was received on these accounts - was received over the past few days and for the simplest and most unremarkable posts.
