What are these accounts 'addon_stspg-jira-ops', 'addon_jira-trello-integration' and addon_cello

Hi, 

I am observing few new jira accounts added to my cloud instance with 'addon_stspg-jira-ops', 'addon_jira-trello-integration' and addon_cello'.  As per app audit logs, 'Installed app Trello' and 'Installed app Jira Service Desk Widget' are by 'anonymous' user.

These ‘users’ are associated with addons. In most (all?) cases when you install and addon then a user associated with the addon is added automatically. This allows the addon to be able to perform the necessary functions. They do not count against license fees.

Thanks Jack. One strange thing is, will these accounts will be removed and added to my cloud instance by any chance. Why because recently we noticed that the above accounts were removed and added automatically.
