Is considered exploit buying cheaper from NPCs and selling for high prices on GTN?

When someone use you referral link and you get the cartel credits, in the Cartel Coins tab on the website, the only description you get is Friends Referral Grant, date, the amount and your balance, it gets out of control when a lot of people uses you referral link and you want to manage it, the suggestion would be that in the description it shows Friends Referral Grant - (Login of player), you know the login of the people that used your referral link through Refer a Friend tab, but in the Cartel Coins tab you don't really know who used.

A suggestion from 2014, it's 2019 and the UI/UX still is pretty terrible and outdated, really hope the team could revise the UI for a less intrusive one, make it more compact, new colors or just more modular so the community can change it easily.
