More info, I analyzed my sponsored ad history and I ran 57 successful ads before October 11 when the first ad was stopped. Since then I have attempted 34 ad campaigns and 30 of those were stopped. My last successful ad was Nov 6 and since then the system has stopped 21 ads.
I have an ongoing test ad for 50 robux per day for 7 days that I keep in my account. Usually the system stops it after a few hours. My theory is if this starts to succeed, I will have some way to know when it is safe to use the broken system again.
Possibly related: I cannot see the Sponsored Ad option in the dropdown on my Robux transactions page.
I hope there is not some corrupted data or something causing my Roblox account to not act normally. If this is an act of moderation I have not been notified, and I double checked my Spam folder to be sure.
It started happening pretty regularly around Oct 11, which does not coincide with when my experience was translated to Turkish language, which was Oct 24.
/cc @Focia19 please pass this info on to the engineer, and I would appreciate a swift resolution, thanks as always for your help with this important matter.
