Once in a while, someone will pop into my community and ask members to fill out some survey. If the first time I hear of you and your survey is from reading a public post that you made in the community, that is not a good look for you.
I’m fairly protective of the community when it comes to people taking advantage of them. While our members are a great resource, the community doesn’t exist to fill out surveys for people. If you wish to utilize the community in this way, you really should ask the manager first and receive permission for doing so.
It’s a courteous, respectful thing to do. You don’t want to assume that your request is acceptable and if you post it and it is not, it’ll be removed. If your request is appropriate, having the stamp of approval from the manager can help you to get more responses as members know that it is alright.
