Zeev: Tagging their alias in color allows for easy identification of subscription gurus or paid promoters and or bashers. Not because they are doing anything illegal, in some cases maybe immoral....gg
The color coding would help members be more aware of who they are reading, so members can make a more informed decision about what they read by these gurus and paid promoters/bashers. IMO, there is nothing wrong with members being cautious of the possibility of underlying self-promotion motivating the posts.
