Hello reneefromchgo,
Thanks for visiting the Apple Support Communities. Reporting this won't stop you from receiving future messages from that sender. This is explained in this help article:
Block phone numbers and contacts on your iPhone, iPad, or iPod touch
You can report iMessages that look like spam or junk from the Messages app. If you get an iMessage from someone who's not saved in your Contacts, you'll see a Report Junk link under the message. Tap Report Junk, then tap Delete and Report Junk. Messages will forward the sender's information and the message to Apple, as well as delete the message from your device. You can't undo deleting a message.
Reporting junk doesn't block the sender from being able to send another message. If you don't want to receive these messages, you need to block the contact.
To report SMS and MMS messages, contact your carrier.
Since this isn't one you do not wish to block, I recommend not doing anything as you will receive the next message from the sender as long as you didn't block them. If you did block them, it will be shown in Settings > Messages > Blocked.
Thanks and have a wonderful day.
