  • As noted elsewhere, do everything you can to avoid handing your card to anyone.

    Use tap to pay wherever possible, then chip - neither of those methods give the card number to the merchant. Do not swipe unless you absolutely have to, and then inspect what you are swiping to make sure nothing is attached to the card reader.

    For online purchases, do everything you can to avoid giving your card number to anyone - use ApplePay / GooglePay / Amazon Pay / PayPal etc. wherever possible. These can be used to put charges on your card without giving your card # to the merchant. These are one-time authorizations (unless you explicitly identify it as a subscription / recurring charge), so they can’t reuse the transaction token they get.




  • Kind of. My observed behavior of Lemmy, combined with comments from some developers (I haven’t read the code):

    Post goes up on community hosted on instance A, Message goes out to B and C: “here’s a new post”

    User x@B comments on post. Message goes from B to A saying “here’s a new comment”. A adds the comment, then sends a message to C “here’s a new comment”

    User y@C upvotes the comment. Message goes from C to A, then A sends a message to C.

    Each of those messages are confirmed by the recipient, and there are timed retries. However, there have been plenty of cases where one of those messages get lost, and the communities get out of sync. As I understand it, the message traffic is only changes. They don’t talk to each other to see what the current state of the content is. So whenever a sync break happens, it is permanent. New content/changes are fine, but stuff that gets lost in transit is lost for good.



  • I can’t speak for the posting bots, but game day bots are pretty fundamental to sports communities - like, we have no shot at attracting any interest to our community if there aren’t game day bots. We’re literally running the same code as the reddit bots, just using the lemmy API. So that same traffic exists on Reddit, it is just that there is so much other traffic that they aren’t as prominent.
