I've heard of multiple people who have done the same and have had the same problem. It seems either so many people are requesting their data that it's bogging down the process, Reddit is deliberately slow-playing it, or both.
Does one have to be an EU citizen to request via GDRP?
If so - I made the offer to sell my accounts to any GDRP person for $1 such that I can make those requests for data (ill pay more than $1, its just to make it an actual transaction)
I have 17 years of content contributed to reddit... and I'd like to kill it all.
