I don't see any need for people to have multiple threads for different services. All this does is push down other people and takes up so much of the front page ESPECIALLY when combined with bumping via botting. (I'm against this also because if you're not able to bump it yourself you're not able to take orders surely so what do you need to be first page for, but we'll ignore this for now)
Many people combine services such as Firecapes/PC/BA/Levelling/Questing all into one thread successfully so I don't see any reason why people should have multiple threads separating them all up. The only reason is that they get more coverage and push others out of view and I don't think it should be allowed.
There are only 6 spaces available on the front page as it stands. People such as DBuffed and Lost Panda already have everything combined however all it would take is two people auto-bumping three threads and you're already second page. I'd love to be able to look at the front page and see 6 different active service owners.
This is all my opinion and I'm open to any other perspective. I don't stand to make any gain myself from this.
Apologies if this has already been addressed or discussed previously.
Edit: One possible secondary solution: Extend the Bump Rule to per section rather than per thread. This way threads wouldn't be removed but it wouldn't allow the same level of dominance from a single person. If they wish to keep multiple threads they can prioritise which they wish to bump and have more coverage. Just a thought.
