And here is some more about what they may do.
Member-to-member contact policy overview
Members can send messages to each other through eBay. We encourage open communication between our members but we don't allow our members to use these options to send spam,
offers to buy or sell off eBay, threats, profanity, or hate speech. We also don't allow members to offer, reference, or request email addresses, phone numbers or other contact information, physical addresses, web addresses, or links within eBay messaging systems (Best Offer, My Messages etc.). eBay may monitor messages sent through eBay and between users for fraud, abuse, spam, and other violations of eBay's policies.
Make sure you follow these guidelines. If you don't, you may be subject to a range of actions, including your messages being blocked, limits of your buying and selling privileges and suspension of your account.
Please remember that we don't have control over communication unless it takes place through eBay. Also, posts on
eBay discussion boards - opens in new window or tab aren't covered by this policy. However, we do have a
Community content policy.
