Hey,
since we do have an official topic to look for roleplay partners (current thread:
viewtopic.php?f=85&t=3515799 ) it would only cause unnecessary spam if everyone would create their own topic to find roleplay partners.
Having one topic for all also makes it easier for users to find roleplay partners. Instead of clicking one topic after another you have them all in one topic and can scroll through without any trouble.
I hope this could answer your question. Please let me know if anything should be unclear.
