On the next page (shown below), there will be a variety of filter options for you to choose from.
Once you have chosen your filters, click the Change Preferences button.
There will be a button of a circle with a line through it (i.e., the "no" symbol) at the upper right of the IM window which says "block", if you mouse over it.
You can also block a member if he or she has nudged you.
Or, the member may not have time to talk and, therefore, refused your request.
In either case, you might want to try again at another time…or find another member to chat with.
Finally, click the Remove Block link next to the person you would like to unblock.
If you need to unblock multiple users at once, there is also a bulk way to do so on the page.
