Art. 27 of GDPR says that whoever processes data of people located inside the EU (includes storing and deleting in the GDPR definition, with a few exceptions) needs a Representative located inside the EU. This relates to a lot of apps and webpages. The Representative has to answer questions about private data in the name of the processor (who, in this scenario, is not located in the EU), and the Representative is not liable (GDPR says so, but it looks like this is not yet 100% confirmed when you read through various law blogs).
To get such a Representative, one can e.g. rent a service typically for about 100 - 200 EUR per month, and they typically charge another 100 EUR per request (actually, per hour working on a request). This could be quite expensive.
My question is, since to my understanding the Representative just passes requests and answers via mail to the processor (who is outside the EU), couldn't this be any person inside the EU working on much lower cost without real personal risk? The commercial services claim of course that much much work and knowledge is required, but going a few times through the GDPR text, I still see practically a simple mail-forwarding activity as long as the processor provides all required documents in the required form. Businesses inside the EU don't care about this because they get the requests directly, and do the Representative's job by themselves.
