I just got the following message when trying to send a question to a seller:
You've exceeded the maximum number of messages you can send per day. Please wait until tomorrow to send more messages.
I sell a lot on eBay/Amazon and get my stock on eBay, so I often have to ask a lot of questions to find out certain details. I've been doing an exceptional amount of business this time of year due to the holiday season, so I've been buying a lot more to replenish my stock, and therefore asking a lot more questions (unlike many of you, I don't have a drop shipper or anything like that).
Never got a message like this before in all my ~14 years of using eBay. This isn't a complaint about eBay, just something I'm bringing up for the topic of discussion. I guess it's an anti-spam measure. It's a good thing I suppose that a daily messages limit is in place.
