Correct, but many people are not informed enough about the tracking abilities that companies have these days, so they make the mistake of keeping their old smartphone or email accounts and that is how those companies keep sending them information related to gambling.
So it is not surprising that now leaving an addiction behind is becoming more and more difficult, and while it is obvious that it can still be done, it is not as if those companies are making the life of those people any easier.
It should not be easy for these people to give their email account addresses or mobile numbers to other parties so that they will not receive information about offers to play gambling again if they move. This is very important to note so that we will not become victims again because, after all, we want to avoid gambling so we decide to move places. But it will all be useless if their offers still tempt us because we can easily follow them without thinking twice, making our life riskier.
