The GDPR is probably not what you think is, because it barely introduces new stuff, it only enforces what already existed but was ignored because it was based on self-regulation.
There are a number a publications about RGPD explaining that there really nothing to panic about (unless you're a giant conglomerate), it's not going to kill your business unless your business is based on violating privacy and things you should not be doing in the first place because it's been illegal for a while and you had 2 years since the announcement to respect the law.
> If you want none of your personal info on the web, I have a suggestion: Don't participate in forums, social media, etc.
Does not work that way, actually thanks to RGPD it's now: if you don't want to deal with RGPD requests don't collect or process personal data.
