Soundbort's limitations regarding file size and soundboard sizes.
Discord sets some limitations on how large a soundboard can be right now. Then some other limitations must be set by Soundbort to not run out of space too soon and keep providing this service. These are:
Maximum samples in a soundboard
10 default (up to 25 by upvoting the bot on top.gg)
Maximum sample length
30 seconds default (longer soon)
Maximum sample file size
8 MB
Maximum sample name length
30 characters
These limits are subject to change, but if you have taken advantage of the limits, you don't need to worry that your samples will be removed.
