The activity stream shows that because it's my last wall post that was on Facebook. That has nothing to do with us or promotion, I was using our test Facebook account, and the last thing I did, before registering on your site, was log in here. We don't have any hidden messages or sneaky things like that. If you don't want the user's last Facebook wall post to be imported, you can turn that off.
Regarding the avatar, let us do some more testing with JomSocial 2.2. We tested with it immediately when it came out, and everything worked fine. However, we're realizing there are a few configuration settings that have bigger effects than we expected, and need to account for those in our profile plugin. Hopefully, the avatar issue is easy to recreate for us and put out another plugin release today/tomorrow.
As for the support, no problem. It's what we do, and thank you for your subscription. If you'd like to go the extra mile, we'd love a review on the Joomla Extension Directory. It's certainly not required, but very appreciated:

Thanks, and we'll keep you posted on what we find with the avatar!
