It is understandable how you feel. Others have felt the same way, and there are several questions posted asking about how members award Lurve. What we all have found is that it runs the spectrum for reasons, thus making it subjective. It can’t be taken personally.
What can be done is to learn to read between the lines of the OP and respond accordingly. It also helps to know who you can joke with and who you shouldn’t. If it is a new member, try to help them out in a sincere, polite way. Once an individual member has awarded you 100 Lurve points, nothing else counts towards growing your score. New members are a fresh source.
And as @Coloma points out, just be patient. The more contributions, and the better quality that they are, will help to increase your score.
