Since I got some downtime in Denver and trying to get adjusted to the time zone difference:
Add to cart services won't admit to pairs getting cancelled but their customers seem to like to PM me about it when it does happened.
One service in particular had 3-5 people PM me within the span of two weekends. Al.l reporting that their orders along with 50+ others originated from the same IP
These ADD TO CART services is doing everyone a favor - getting people flagged, one sneakerhead at a time.
And for those that plan to blacklist a tweet because the word GS is in tweet should be careful. If the randomly generated swoosh link possesses a GS in it - that tweet might get overlooked.
