One thing you could do is create topics with a broader subject matter.
For instance, rather than creating 30 topics asking specifically about every language of the world or each variation of skin tone a race of people might have, you could create one general topic called "Languages of Europe (Asia, the Americas, Africa, etc.) - Translations Needed" and then list the various languages you are interested in getting help with. That will attract lots of people to your topic at least once to see if they can help with a specific translation.
Make use of existing topics. Use the tag search to see if there are already topics that contain your subject matter and add on to them if applicable. Doing that automatically creates a common bond between you and the members who were already posting on that subject. Make use of those threads to enhance connections with others rather than making threads asking if there are any (fill in the blank) here before asking your question.
When you ask people to respond to your questions and requests for help, express a bit of appreciation for responses rather than using them for a defensive batting practice. Not everyone is going to have a positive response for you. Don't let it ruin your day.
