Are suggestions limited to 50 votes?
In a word, no.
Suggestions are not limited to 50 votes. In practical terms, suggestions are not limited to a certain number of votes.
However, for new boards where many users arrive at your board at once, you might get the impression of there being a 50 vote limit.
What’s happening is that the sudden arrival of many votes triggers our vote throttling. Our system for preventing voting manipulation thinks something suspicious is happening.
What you can do: Temporarily relax the vote throttling the level.
In general, we recomend you don’t turn off the vote throttling unless you have a good reason for doing so.
