"bump"

[Nicolas]

Some recent replies I have made to posts in the enquiries section have been renegaded to the 'trash can' with no explanation aside from 'bump'.
I am annoyed because I am not 'bumping' I am genuinely registering my oppinion in response to a topic. I don't get a chance to visit AHS and enjoy the enquiries section and I reply regardless of how old a topic is. Why would I bump a topic I didn't even start, especially when I am adding something new to it? And why store topics from years ago if you don't want people to reply to them? Locking them would prevent people like me...'bumping'.
I have looked through the rules section and couldn't see ay guidelines on bumping but perhaps I need to look again?
Please let me know and if you would be so kind, please restore my replies as I feel they were of value.
