Actually I did that yesterday, like more than 24 hours ago, and the reason is because I don't agree with tagging people for old offenses unless their account is currently engaged in sketchy activity.
Alright, that's a cometely valid point of view.
My stance is that these accounts (who showed untrustworthy behavior) should be tagged regardless of whether they are currently involved in sketchy stuff or not, except in the case where there are proven to be trustworthy at the current date.
This was also the reason why - for example - i felt it would be inappropriate to start negative actions against you since you have proven to be a reputable and trustworthy member of this community.
After going a year and five months without leaving a single feedback you've left 22 negative feedbacks in the last 16 days, some are for account sales in 2016/17. You left a total of 5 feedbacks in your 3 years here before that. That kind of behavior is a bit odd to me, but you know, you're free to do as you will.
I understand this.
The reason for my actions is that I have decided to shift my attention on this forum from the technical support to the reputation section. Not completely, but i will try to make this forum a better - and less scammy - place.
However, thanks for being honest and explaining your actions!
