I’m not sure one message counts as spamming you? Might have missed an opt out though
It was meant as a joke.
Although seriously, I doubt it’s in the spirit of GDPR to send me this without my consent (or, as you say, an opt out).
Me and jokes… yeah
Could be you did opt in for communication regarding important notices
While I’m doubtful, it is possible.
But then it’s so difficult to find out who you gave consent to for almost anything…
