You only mentioned the 100TB plan limit, this is why I suggested
AccountingMax. I couldn't have guessed you are talking about some
other policy limits.

The consensus weight is your bandwidth measured by the bandwidth
authorities. This is used by clients to calculate your relay's
probability from being chosen in a circuit. If it's big, yes of course
it will attract more clients. If you rate-limit it in torrc, the
bandwidth authorities won't be able to measure more than what you are
offering. Maybe use this:

MaxAdvertisedBandwidth N bytes|KBytes|MBytes|GBytes|KBits|MBits|GBits

    If set, we will not advertise more than this amount of bandwidth
for our BandwidthRate. Server operators who want to reduce the number
of clients who ask to build circuits through them (since this is
proportional to advertised bandwidth rate) can thus reduce the CPU
demands on their server without impacting network performance.
