I stick to email and haven't experienced this yet. I did make the mistake of entering my email for a random peptide website to see their price list after seeing a FB ad for a Labor Day buy one, get two free promotion. I was just curious what the price came out to, as it didn't say. Yesterday, I received 25 spam messages from totally different companies all about glucose strips and various diabetes websites. That was not a coincidence. Lesson learned: Never enter your email to see a price list, either.
