I will not be flagging any steemtrails. At this point I am watching to see what they do. Their plan for delegating power to many accounts seems potentially positive. I know they've offered training and engagement for a lot of new users.
I will watch for abuse. If as you are indicating there is indeed a problem then I will remove my support. I don't need to flag them if there is an issue. I simply could remove support.
The potential for abuse is there. It is definitely worth being on the look out for.
I've seen some of their plans on how they plan to use some of that power they have been amassing and if it is used like they indicate it could be positive for growth, and for a lot of lesser known posts.
Thank you for bringing it to my attention, for at the very least I will be paying a lot more attention. I have lended my support to them for awhile now though I don't actively help or up vote any specific trails. If it is indeed being abused then I would remove such support.
