I am seeing it from a very different angle.
These limits are usually there to stop people from scraping data and causing trouble. If it was unlimited or 100 per day, think of how much data you can scrap with-in a month? all those 3000 legit contacts with-in a month, and also know which car they are selling and where they from.
On a personal note, I tend to lose track of who I'm talking to after reaching out to about 10 people in a single day. If the need arises to go beyond 25, I'd simply create another account for that or create a fake account.
