I like what @Brylan_Leske said about a cut on transferred fees thru the site. Regardless what value this ‘placeholder fee’ your guys’ method of payment thru transactions (‘commissions’ is more 1-1 mutual agreement of payment and not really based off a team which is what this service can be used for), the general method of this fee is SCAMMY.
Roblox already takes 20% revenue from Robux purchases (AND DevEx) so you guys getting Robux for your own DevEx transactions #1 means you guys are gaining no positive profit and #2 that placeholder or unknown amount of robux someone on your site is being forced a tip going to a not even garunteed DevEx transaction in the future for you guys. (Elaborating on this point, if you guys are getting small little transactions of robux regardless of amount it’s gonna take an incredible amount of time to actually earn a worthwhile amount of robux and spread it evenly between the 3 of you.)
However I think organization and security is a great idea here and it’s all a real thing about scamming and stuff- but that really depends more on the person than roblox itself. Cause in the end I don’t think I’ve seen anything that you’ve shown directly to help scamming/malicious activity. What makes fiverr or other methods not as great as this one anyways?
One suggestion tho is that you guys could implement a subscription service, so that you could have an actual guaranteed method of money (and more reliable too if its not based on robux) and lock your guys’ ‘specialty features’ or unique helping factors to those using this site thru this subscription. Aside from this just reading all the comments- where you guys are heading is pretty scammy and wont be very successful in the long run.
