Cleanup is standard work for any dataset. With enough money and a pile of Indians working for cheap hourly rates you can clean through A LOT of data. 10,000? Try a million!
But, my suspicion is that everyone on beermoney actually has no other income :(
Do I have a choice about whether or not I have to hold down a job? No. No I don’t.
Do I have a choice about the level of competition I must bring to the table to simply tread water? No. No I don’t.
If I had a choice, I’d never program another piece of code again, but hey. Yeah, beer money. Like I have a life whereupon I enjoy it enough to drink beer.
I dont know what you think gdpr is but it's not a magic wand which prevents companies from gathering data.
