I’m not a huge fan of Twitter’s new blocking scheme. These two posts do a great job of explaining why:
Blocking, even on a public account, is surprisingly effective at dealing with low-grade harassment. Most harassers just aren’t that invested in the person they are bothering, and putting up the tiniest roadblock will make them move on to their next target. I had this conversation with a Googler shortly after G+ shipped, as its blocking behavior was at the time the same as the new Twitter behavior. I have no idea what it is now because I hate G+ and don’t use it, and I realized that this may be unintuitive to someone who hasn’t experienced harassment before – but trust me, as someone who has, it works a lot of the time. Which is great!
Unfortunately, by enacting this policy change, more people will simply lock their accounts to bring back the capabilities of the “old” block. Not exactly the transparency Twitter is hoping for.
