Currently, materials stop at 2,000 messages and 800 likes. However, plenty of people are way over that limit, and I think they deserve to be rewarded. Obviously, this can't go indefinitely, so maybe go to at least 10,000 messages and 2,000 likes? Or add more materials as message and like counts increase. For example, if you only have materials up to 1,000 messages and 500 likes, when several people start getting to, say, 1,500 messages and 1,000 likes, add materials for 2,000 messages and 1,500 likes.
Materials actually stop at 4,000 messages and 800 likes. Regardless, the Material System has become somewhat obsolete in its current state. There are a few things I have planned for it, but in the time being it's not going to get any more "materials." What you do have will be re-usable, and there will be additions, but right now it's in rehaul.
